The ’FCT163T devices are high-speed
NC – No internal connection
synchronous modulo-16 binary counters. They
are synchronously presettable for application in
programmable dividers. These devices have two
types of count-enable (CEP and CET) inputs, plus a terminal-count (TC) output for versatility in forming
synchronous multistaged counters. The ’FCT163T devices have a synchronous-reset (SR) input that overrides
counting and parallel loading, and...
