74HC699 Overview
Description
The HC696/697 are high speed CMOS up/down counters fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
Key Features
- enable P and enable T and a ripple-carry output for easy expansion
- Both the counter clock CCK and register clock RCK are positive-edge triggered
- The counter clear CCLR is active low and is synchronous for HC698/699, and asynchronous for HC696/697
- All inputs are equipped with protection circuits against static discharge and transient excess voltage
