HIGH-SPEED CMOS 10-BIT

BUS SWITCH WITH

FLOW-THROUGH PINOUT

DESCRIPTION:

FEATURES:

The QS3861 provides a set of ten high-speed CMOS TTL-compatible

bus switches. The low ON resistance (5Ω) of the QS3861 allows inputs to

be connected without adding propagation delay and without generating

additional ground bounce noise. The Bus Enable (BE) signal turns the

switcheson.

• Enhanced N channel FET with no inherent diode to Vcc

• 5Ω bidirectional switches connect inputs to outputs

• Zero propagation delay, zero ground bounce

• Undershoot clamp diodes on all switch and control inputs

• Available in SOIC, QSOP, and TSSOP packages

The QS3861 is characterized for operation at -40°C to +85°C.

APPLICATIONS:

• Hot-swapping, hot-docking

• Voltage translation (5V to 3.3V)

• Power Conservation

• Capacitance reduction and isloation

• Bus Isolation

• Clock Gating

NOTES:

1. Minimums are guaranteed but not production tested.

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 0.25ns at C^L= 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.
