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.
