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.

Notes:
1.
H = HIGH Voltage Level. L = LOW Voltage Level. X = Don't Care.
2.
Unless otherwise noted, these limits are over the operating free-air temperature range.
3.
Unused inputs must always be connected to an appropriate logic voltage level, preferably either V
CC
or ground.
4.
T
A
is the "instant on" case temperature.
5.
Typical values are at V
CC
=5.0V, T
A
=+25C ambient.
6.
This parameter is specified but not tested.
7.
Not more than one output should be shorted at a time. Duration of short should not exceed one second. The use of high-speed test apparatus and/or sample
and hold techniques are preferable in order to minimize internal chip heating and more accurately reflect operational values. Otherwise prolonged shorting of
a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parametric tests. In any sequence of parameter
tests, I
OS
tests should be performed last.
