M54HC697 HC697/699 U/D 4 BIT BINARY COUNTER/REGISTER 3-STATE HC696/698 U/D DECADE COUNTER/REGISTER 3-STATE

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. The HC696/698 are BCD DECADE COUNTER, and the HC697/699 are 4-BIT BINARY COUNTER. Both.

* enable P and enable T and a ripple-carry output for easy expansion. the register/counter select input, R/C, selects the counter when low or the register when high for the three state outputs, QA, QB, Qc and QD. Both the counter clock CCK and register clock RCK are positive-edge triggered. The counte
