Quad 2−Input XOR Gate /
CMOS Logic Level Shifter
with LSTTL−Compatible Inputs
http://onsemi.com
The MC74VHCT86A is an advanced high speed CMOS 2−input
Exclusive−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 5V 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
3.0V CMOS logic to 5.0V CMOS Logic or from 1.8V CMOS logic to
3.0V CMOS Logic while operating at the high−voltage power supply.
The MC74VHCT86A input structure provides protection when
voltages up to 7V are applied, regardless of the supply voltage. This
allows it to be used to interface 5V circuits to 3V circuits. The output
