1. General description

The 74LV32A is a quad 2-input OR gate.

Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed

voltage 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.
