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.

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.
