DESCRIPTION/ORDERING INFORMATION  
The PCA9518 is an expandable five-channel bidirectional buffer for I2C and SMBus applications. The I2C  
protocol requires a maximum bus capacitance of 400 pF, which is derived from the number of devices on the I2C  
bus and the bus length. The PCA9518 overcomes this restriction by separating and buffering the I2C data (SDA)  
and clock (SCL) lines into multiple groups of 400-pF segments. Any segment-to-segment transition sees only  
one repeater delay. Each PCA9518 can communicate with other PCA9518 hubs through a 4-wire inter-hub  
expansion bus. Using multiple PCA9518 parts, any width hub (in multiples of five) can be implemented using the  
expansion pins, with only one repeater delay and no functional degradation of the system performance.

EXPANDABLE FIVE-CHANNEL I2C HUB  
www.ti.com  
SCPS132AJUNE 2006REVISED JULY 2007  
DESCRIPTION (CONTINUED)  
The device is designed for 3-V to 3.6-V VCC operation, but it has 5-V tolerant I2C and enable (EN) input pins.  
This feature allows for translation from 3 V to 5 V between a master and slave. The enable pin also can be used  
to electrically isolate a repeater segment from the I2C bus. This is useful in cases where one segment needs to  
run at 100 kHz while the rest of the system is at 400 kHz. If the master is running at 400 kHz, the maximum  
system operating frequency may be less than 400 kHz, because of the delays added by the repeater.  
The output low levels for each internal buffer are approximately 0.5 V, but the input voltage of each internal  
buffer must be 70 mV or more below the output low level, when the output internally is driven low. This prevents  
a lockup condition from occurring when the input low condition is released.  
A PCA9518 cluster cannot be put in series with a repeater such as the PCA9515 or another PCA9518 cluster,  
as the design does not allow this configuration. Multiple PCA9518 devices can be grouped with other PCA9518  
devices into any size cluster using the EXPxxxx pins that allow the I2C signals to be sent or received from one  
PCA9518 to another PCA9518 within the cluster. Because there is no direction pin, slightly different valid low  
voltage levels are used to avoid lockup conditions between the input and the output of individual repeaters in the  
cluster. A valid low applied at the input of any of the PCA9518 devices is propagated as a buffered low, with a  
slightly higher value, to all enabled outputs in the PCA9518 cluster. When this buffered low is applied to another  
repeater or separate PCA9518 cluster (not connected via the EXPxxxx pins) in series, the second repeater or  
PCA9518 cluster does not recognize it as a regular low and does not propagate it as a buffered low again. For  
this reason, the PCA9518 should not be put in series with other repeater or PCA9518 clusters.  
The PCA9518 has five multidirectional open-drain buffers designed to support the standard low-level-contention  
arbitration of the I2C bus. Except during arbitration or clock stretching, the PCA9518 acts like a pair of  
noninverting open-drain buffers, one for SDA and one for SCL.  
There is an internal power-on-reset circuit (VPOR) that allows for an initial condition and the ramping of VCC to set  
the internal logic.  
As with the standard I2C system, pullup resistors are required on each SDAn and SCLn to provide the logic high  
levels on the buffered bus. The size of these pullup resistors depends on the system, but it is essential that each  
side of the repeater have a pullup resistor. The device is designed to work with standard-mode and fast-mode  
I2C devices in addition to SMBus devices. Standard-mode I2C devices only specify 3 mA in a generic I2C system  
where standard-mode devices and multiple masters are possible.

Enable  
EN1–EN4 are active-high enable pins and have internal pullup resistors. Each enable pin, ENn, controls its  
associated SDAn and SCLn ports. When ENn is low, it isolates its corresponding SDAn and SCLn from the  
system by blocking the inputs from SDAn and SCLn and disabling the output drivers on the SDAn and SCLn  
pins. It is essential that the ENn change state only when both the global bus and the local port are in an idle  
state to prevent system failures. EN1–EN4 also allow the use of open-drain drivers that can be wire-ORed to  
create a distributed enable where either centralized control signal (master) or spoke signal (submaster) can  
enable the channel when it is idle.  
Expansion  
The PCA9518 has four open-drain I/O pins used for expansion. The internal state of the serial data within each  
hub is communicated to other hubs through two expansion pins, EXPSDA1 and EXPSDA2. The EXPSDA1 pins  
of all hubs are connected together to form an open-drain bus. Similarly, all EXPSDA2 pins, EXPSCL1 pins, and  
EXPSCL2 pins are connected together, forming a 4-wire bus between hubs. When it is necessary to be able to  
deselect every port, each expansion device contributes only four ports that can be enabled or disabled; the fifth  
port does not have an enable pin. Pullup resistors are required on the EXPxxxx pins, even if only one PCA9518  
is used.

(1) The SDA and SCL propagation delays are dominated by rise times or fall times. The fall times mostly are internally controlled and are  
sensitive only to load capacitance. The rise times are RC time-constant controlled and, therefore, a specific numerical value can be  
given only for fixed RC time constants.  
(2) The SDA high-to-low propagation delay, tPHLs, includes the fall time from VCC to 0.5 VCC of EXPSDA1 or EXPSCL1 and the SDA or SCL  
fall time from the quiescent high (usually VCC) to below 0.3 VCC. The SDA and SCL outputs have edge-rate-control circuits included that  
make the fall time almost independent of load capacitance.  
(3) The SDA or SCL low-to-high propagation delay, tPLHs, includes the rise-time constant from the quiescent low to 0.5 VCC for EXPSDA1 or  
EXPSCL2, the rise-time constant for the quiescent low to 0.5 VCC for EXPSDA1 or EXPSCL1, and the rise time constant from the  
quiescent externally driven low to 0.7 VCC for SDA or SCL.

A. Only two of the five channels of the PCA9518 device 2 are being used. EN3 and EN4 are connected to GND to  
disable channels 3 and 4, or SDA3/SCL3 and SDA4/SCL4 are pulled up to VCC. SDA0 and SCL0 can be used as a  
normal I2C port, but they must be pulled up to VCC if unused, because there is no enable pin.  
Figure 3. Multiple Expandable Five-Channel I2C Hubs  
Here, the system master is running on a 3.3-V I2C bus, while the slaves are connected to a 3.3-V or 5-V bus.  
The PCA9518 is 5-V tolerant, so it does not require any additional circuitry to translate between the different bus  
voltages.  
All buses run at 100 kHz, unless slaves 3, 4, and 5 are isolated from the bus. If the master bus and slaves 1, 2,  
and 6 need to run at 400 kHz, slaves 3, 4, and 5 can be isolated through the bus master. In this case, the bus  
master will change the state on the corresponding EN pin (for slaves 3, 4, and 5) to low.  
Any segment of the hub can talk to any other segment of the hub. Bus masters and slaves can be located on  
any segment with 400-pF load allowed on each segment.  
When one port of the PCA9518 is pulled low by a device on the I2C bus, a CMOS hysteresis-type input detects  
the falling edge and drives the EXPxxx1 line low; when the EXPxxx1 voltage is less than 0.5-V VCC, the other  
ports are pulled down to the VOL of the PCA9518, which is typically 0.5 V.

Figure 4. Bus Waveforms  
Note that any arbitration or clock-stretching events on bus 1 require that the VOL of the devices on bus 1 be  
70 mV below the VOL of the PCA9518 (see VOL – VILc in electrical characteristics) to be recognized by the  
PCA9518 and transmitted to bus 0.  
This looks like a normal I2C transmission, except for the small step preceding each clock low-to-high transition  
and proceeding each data low-to-high transition for the master. The step height is the difference between the  
low level driven by the master and the higher-voltage low level driven by the PCA9518 repeater. Its width  
corresponds to an effective clock stretching coming from the PCA9518, which delays the rising edge of the  
clock. That same magnitude of delay is seen on the rising edge of the data. The step on the rising edge of the  
data is extended through the ninth clock pulse as the PCA9518 repeats the acknowledge from the slave to the  
master. The clock of the slave looks normal, except that the VOL is the 0.5-V level generated by the PCA9518.  
The SDA at the slave has a particularly interesting shape during the ninth clock cycle, when the slave pulls the  
line below the value driven by the PCA9518 during the ACK and then returns to the PCA9518 level, creating a  
foot before it completes the low-to-high transition. SDA lines, other than the one with the master and the one  
with the slave, have a uniform low level driven by the PCA9518 repeater.

APPLICATION INFORMATION (continued)  
The expansion bus signals shown in Figure 4 are included primarily for timing reference points.  
All timing on the expansion bus is with respect to 0.5 VCC. EXPSDA1 is driven low whenever any SDA pin falls  
below 0.3-V VCC and EXPSDA2 is driven low when any pin is 0.4 V. EXPSCL1 is driven LOW whenever any  
SCL pin falls below 0.3-V VCC and EXPSCL2 is driven LOW when any SCL pin is 0.4 V. EXPSDA2 returns high  
after the SDA pin that was the last one being held below 0.4 V by an external driver starts to rise. The last SDA  
to rise above 0.4 V is held down by the PCA9518 to 0.5 V until after the delay of the circuit that determines that  
it was the last to rise; then, it is allowed to rise above the 0.5-V level driven by the PCA9518.  
Considering the bus 0 SDA to be the last one to go above 0.4 V, then EXPSDA1 returns to high after EXPSDA2  
is high and either bus 0 SDA rise time is 1 μs or bus 0 SDA reaches 0.7-V VCC, whichever occurs first. After  
both EXPSDA2 and EXPSDA1 are high, the rest of the SDA lines are allowed to rise. The same description  
applies to the EXPSCL1, EXPSCL2, and SCL pins.  
Any arbitration or clock stretching events on bus 1 requires that the VOL of the devices on bus 1 be 70 mV below  
the VOL of the PCA9518 (see VOL – VILc in electrical characteristics) to be recognized by the PCA9518 and then  
transmitted to bus 0.
