74HC163D - Presettable synchronous 4-bit binary counter
The 74HC163; 74HCT163 is a synchronous presettable binary counter with an internal look-head carry.
Synchronous operation is provided by having all flip-flops clocked simultaneously on the positive-going edge of the clock (CP).
The outputs (Q0 to Q3) of the counters may be preset to a HIGH or LOW.
