4-bit bus switch

Rev. 5 — 9 October 2018

Product data sheet

1. General description

The 74CBTLV3126 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 minimum value of the resistor is determined by the

current-sinking capability of the driver.

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.
