4-bit bus switch

Rev. 3 — 9 October 2018

Product data sheet

1. General description

The 74CBTLV3126-Q100 provides a 4-bit high-speed bus switch with separate output enable

inputs (1OE to 4OE). The low on-state resistance of the switch allows connections to be made with

minimal propagation delay. The switch is disabled (high-impedance OFF-state) when the output

enable (nOE) input is LOW.

To ensure the high-impedance OFF-state during power-up or power-down, nOE should be tied to

the GND through a pull-down resistor. The current-sinking capability of the driver determines the

minimum value of the resistor.

Schmitt trigger action at control input makes the circuit tolerant to slower input rise and fall times

across the entire V_CCrange from 2.3 V to 3.6 V.

This device is fully specified for partial power-down applications using I_OFF. The I_OFFcircuitry

disables the output, preventing the damaging backflow current through the device when it is

powered down.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
