Synchronous 4-Bit Binary Counter

The \x92FCT163T devices are high-speed 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 \x92FCT163T devices have a synchronous-reset (SR\) input that overrides counting and parallel loading, and allows the outputs to be reset simultaneously on the rising edge of the clock.

These devices are fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
