SN74F163A Datasheet (Texas Instruments) - SYNCHRONOUS 4-BIT BINARY COUNTER

SN74F163A, SYNCHRONOUS 4-BIT BINARY COUNTER

This synchronous, presettable, 4-bit binary counter has internal carry look-ahead circuitry for use in high-speed counting designs.

Synchronous operation is provided by having all A3 B4 C5 D6 ENP 7 GND 8 14 QA 13 QB 12 QC 11 QD 10 ENT 9 LOAD flip-flops clocked simultaneously so that the outputs

* a fully independent clock circuit. Changes at ENP, ENT, or LOAD that modify the operating mode have no effect on the contents of the counter until clocking occurs. The function of the counter (whether enabled, disabled, loading, or counting) is dictated solely by the conditions meeting the setup and
