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 dissipation. The VHC161 is a high-speed
synchronous modulo-16 binary counter. This device is
synchronously presettable for application in program-
mable 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
prevents device destruction due to mismatched supply
and input voltages.
Ordering Information
Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the
ordering number.
