MC74VHCT32A
Quad 2-Input OR Gate /
CMOS Logic Level Shifter
with LSTTL − Compatible Inputs
The MC74VHCT32A is an advanced high speed CMOS 2−input
OR gate fabricated with silicon gate CMOS technology. It achieves
high speed operation similar to equivalent Bipolar Schottky TTL
while maintaining CMOS low power dissipation.
The internal circuit is composed of three stages, including a buffer
output which provides high noise immunity and stable output.
The device input is compatible with TTL−type input thresholds and
the output has a full 5.0 V CMOS level output swing. The input
protection circuitry on this device allows overvoltage tolerance on the
input, allowing the device to be used as a logic−level translator from
3.0 V CMOS logic to 5.0 V CMOS Logic or from 1.8 V CMOS logic
to 3.0 V CMOS Logic while operating at the high−voltage power
supply.

The MC74VHCT32A input structure provides protection when
voltages up to 7.0 V are applied, regardless of the supply voltage. This
allows the MC74VHCT32A to be used to interface 5.0 V circuits to
3.0 V circuits. The output structures also provide protection when
