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
