DESCRIPTION:
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.
