DM74S161 Synchronous 4-Bit Binary Counters

These synchronous presettable counters feature an internal carry look-ahead for application in high-speed counting designs They are 4-bit binary counters The carry output is decoded by means of a NOR gate thus preventing spikes during the normal counting mode of operation Synchronous operation is provided by having all flip-flops clocked simultaneously so th.
