74VHC161 Datasheet (Fairchild Semiconductor)

74VHC161, 4-Bit Binary Counter

The VHC161 is an advanced high-speed CMOS device 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 VHC161 is a high-speed synchronous modulo16 binary counter.
