The IDT74FCT161T is a high-speed synchronous modulo-16 binary counter built using an advanced dual metal CMOS technology. It is synchronously presettable for application in programmable dividers and has two types of count enable inputs plus a terminal count output for versatility in forming synchronous multi-stage counters. The IDT74FCT161T has asynchronous Master Reset inputs that override all other inputs and force the outputs low.
