74LV32A
Quad 2-input OR gate
Rev. 1 — 19 December 2018
Product data sheet
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 I
OFF
. The I
OFF
circuitry
disables the output, preventing the potentially damaging backflow current through the device when
it is powered down.

If the input current ratings are observed, the minimum input voltage ratings may be exceeded.
If the output current ratings are observed, the output voltage ratings may be exceeded.
This value is limited to 7 V maximum.
For SOT402-1 package: above 116 °C, the value of P
tot
derates linearly at 7.3 mW/K.
