9316 - Synchronous 4-Bit Counters

General Description

These synchronous presettable counters feature an internal carry look-ahead for application in high-speed counting designs The 9316 is a 4-bit binary counter The carry output is decoded by means of a NOR gate thus preventing spikes during the normal counting mode of operation Synchronous operation i
