DESCRIPTION:

•
•
The FCT163T is a high-speed synchronous modulo-16 binary counter
built using an advanced dual metal CMOS technology. They are synchronously
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 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. Output and I/O terminals only.
