74LVC126A

Quad buffer/line driver with 5 V tolerant input/outputs; 3-state

Rev. 11 — 20 September 2021

Product data sheet

1. General description

The 74LVC126A is a quad buffer/line driver with 3-state outputs controlled by the output enable

inputs (nOE). A LOW on nOE causes the outputs to assume a high impedance OFF-state. Inputs

can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as

translators in mixed 3.3 V and 5 V environments.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

This device is fully specified for partial power down applications using IOFF. The IOFF circuitry

disables the output, preventing the potentially damaging backflow current through the device when

it is powered down.

2. Features and benefits

• Overvoltage tolerant inputs to 5.5 V

• Wide supply voltage range from 1.2 V to 3.6 V
