74VHC393 Datasheet (Fairchild Semiconductor)

74VHC393, Dual 4-Bit Binary Counter

The VHC393 is an advanced high speed CMOS 4-bit Binary Counter 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.

It contains two independent counter circuits in one package,
