Overview: DATA SHEET www.onsemi.com Quad 2-Input XOR Gate
MC74VHC86, MC74VHCT86A
The MC74VHC86 and MC74VHCT86A are high speed CMOS 2−input Exclusive−OR gates fabricated with silicon gate CMOS technology. These achieve high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation.
The MC74VHC86 inputs are compatible with standard CMOS levels while the MC74VHCT86A inputs are compatible with TTL levels. This device can be used as a level converter for interfacing 3.3 V to 5.0 V, because it has full 5.0 V CMOS level output swings.
The MC74VHC86 and MC74VHCT86A internal circuits are composed of three stages, including a buffer output which provides high noise immunity and stable output. The input structures tolerate voltages up to 5.5 V, allowing the interface of 5 V systems to 3 V systems.
The MC74VHCT86A output structures provide protection when VCC = 0 V. These output structures help prevent device destruction caused by supply voltage − input/output voltage mismatch, battery backup, hot insertion, etc.
