DESCRIPTION:

The FCT163T is a high-speed synchronous modulo-16 binary counter

built using an advanced dual metal CMOS technology. They are synchro-

nously presettable for application in programmable dividers and have two

types of count enable inputs plus a terminal count output for versatility in

forming synchronous multi-stage counters. The FCT163T has Synchro-

nous Reset inputs that override counting and parallel loading and allow the

outputs to be simultaneously reset on the rising edge of the clock.
