Functional Description
The FCT163T is a high-speed synchronous modulo-16 binary
counter. It is synchronously presettable for application in pro-
grammable dividers and has two types of count enable inputs
plus a terminal count output for versatility in forming synchro-
nous multi-staged counters. The FCT163T has a Synchronous
Reset input that overrides counting and parallel loading and
allows the outputs to be simultaneously reset on the rising
edge of the clock.
The outputs are designed with a power-off disable feature to
allow for live insertion of boards.
