4位二进制计数器具有异步清零 4-Bit Binary Counter with Asynchronous Clear
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% VCCmin
■Power down protection provided on all inputs
■Low noise: VOLP =0.8V max
■Pin and function compatible with 74HC161
