DESCRIPTION:
The IDT54/74FCT161T/163T, IDT54/74FCT161AT/ 163AT
and IDT54/74FCT161CT/163CT are high-speed synchro-
nous modulo-16 binary counters built using an advanced dual
metal CMOS technology. They are synchronously preset-
table 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
IDT54/74FCT161T/AT/CT have asynchronous Master Reset
inputs that override all other inputs and force the outputs LOW.
The IDT54/74FCT163T/AT/CT have Synchronous Reset in-
puts that override counting and parallel loading and allow the
outputs to be simultaneously reset on the rising edge of the
clock.

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-
INGS may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other condi-
tions above those indicated in the operational sections of this specifica-
tion 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. Input and VCC terminals only.
3. Outputs and I/O terminals only.
