74LVC2G126

Dual bus buffer/line driver; 3-state

Rev. 15 — 28 April 2020

Product data sheet

1. General description

The 74LVC2G126 is a dual buffer/line driver with 3-state outputs controlled by the output enable

inputs (nOE). 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.
