IDT54/74FCT163T/AT/CT
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/AT/CT has
Synchronous Reset inputs that override counting and parallel loading and
allow the outputs to be simultaneously reset on the rising edge of the clock.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or
any other conditions above those indicated in the operational sections
of this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
No
terminal voltage may exceed Vcc by +0.5V unless otherwise noted.
2. Inputs and Vcc terminals only.
3. Outputs and I/O terminals only.
