74VHC161
4-Bit Binary Counter with Asynchronous Clear
General Description
The VHC161 is an advanced high-speed CMOS device
fabricated with silicon gate CMOS technology. It achieves
the high-speed operation similar to equivalent Bipolar
Schottky TTL while maintaining the CMOS low power dissi-
pation. The VHC161 is a high-speed synchronous modulo-
16 binary counter. This device is 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 multistage counters.
The VHC161 has an asynchronous Master Reset input that
overrides all other inputs and forces the outputs LOW. An
input protection circuit insures that 0V to 7V can be applied
to the input pins without regard to the supply voltage. This
device can be used to interface 5V to 3V systems and two
supply systems such as battery backup. This circuit pre-
vents device destruction due to mismatched supply and
input voltages.
