IDTQS32XVH245

2.5V / 3.3V 16-BIT HIGH

BANDWIDTH BUS SWITCH

FEATURES:

DESCRIPTION:

• N channel FET switches with no parasitic diode to VCC

– Isolation under power-off conditions

– No DC path to VCC or GND

TheQS32XVH245HotSwitchisahighbandwidth,16-bitbusswitch. The

QS32XVH245 has very low ON resistance, resulting in under 250ps

propagation delay through the switch. The switches can be turned ON

under the control of the LVTTL-compatible Output Enable (OEx) signal for

bidirectional data flow with no added delay or ground bounce. In the ON

state,theswitchescanpasssignalsupto5V. IntheOFFstate,theswitches

offer very high impedence at the terminals.

– 5V tolerant in OFF and ON state

• 5V tolerant I/Os

• Low RON - 4Ω typical

• Flat R^ONcharacteristics over operating range

• Rail-to-rail switching 0 - 5V

The combination of near-zero propagation delay, high OFF impedance,

and over-voltage tolerance makes the QS32XVH245 ideal for high perfor-

mance communications applications.

• Bidirectional dataflow with near-zero delay: no added ground

bounce

• Excellent R^ONmatching between channels

• VCC operation: 2.3V to 3.6V

TheQS32XVH245ischaracterizedforoperationfrom-40°Cto+85°C.5°C.

• High bandwidth - up to 500MHz

• LVTTL-compatible control Inputs

• Undershoot Clamp Diodes on all switch and control Inputs

• Low I/O capacitance, 4pF typical

• Available in 40-pin QVSOP package

APPLICATIONS:

• Hot-swapping

• 10/100 Base-T, Ethernet LAN switch

• Low distortion analog switch

• Replaces mechanical relay

• ATM 25/155 switching

NOTES:

1. See Test Conditions under TEST CIRCUITS AND WAVEFORMS.

2. This parameter is guaranteed but not production tested.

3. The bus switch contributes no propagation delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone is of the

order of 0.2ns at CL = 50pF. Since this time constant is much smaller than the rise and fall times of typical driving signals, it adds very little propagation delay to the system. Propagation

delay of the bus switch, when used in a system, is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side.

4. Minimums are guaranteed but not production tested.

5. Maximum toggle frequency for OEx control input (pass voltage > VCC, VIN = 5V, RLOAD ≥ 1MΩ, no CLOAD).
