General Description
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.

Features
■ High Speed: fMAX =185 MHz (typ) at TA =25°C
■ Synchronous counting and loading
■ High-speed synchronous expansion
■ Low power dissipation: ICC =4 µA (max) at TA=25°C
■ High noise immunity: VNIH =VNIL =28% VCC(min)
■ Power down protection provided on all inputs
■ Low noise: VOLP =0.8V (max)
■ Pin and function compatible with 74HC161
