74VHC27 Datasheet (Fairchild Semiconductor)

74VHC27, Triple 3-Input NOR Gate

The VHC27 is an advanced high speed CMOS 3-Input NOR Gate fabricated with silicon gate CMOS technology.

It achieves the high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.

The internal circuit is composed of 3 stages including buffer outp
