74VHC27 Triple 3-Input NOR Gate July 1994 Revised April 1999 74VHC27 Triple 3-Input NOR Gate General Description 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 output, which provide high noise immunity and stable output. An input protection circuit
