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 I_OFF. The I_OFFcircuitry

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

CMOS low power consumption

Direct interface with TTL levels

Complies with JEDEC standard:

•

JESD8-7A (1.65 V to 1.95 V)

JESD8-5A (2.3 V to 2.7 V)

JESD8-C/JESD36 (2.7 V to 3.6 V)

•

ESD protection:

•

HBM JESD22-A114F exceeds 2000 V

MM JESD22-A115B exceeds 200 V

CDM JESD22-C101E exceeds 1000 V
