4-Bit Binary Counter with Synchronous Clear
General Description
The VHC163 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 VHC163 is a high-speed synchronous modulo-16
binary counter. This device is synchronously presettable for
application in programmable dividers and has two types of
Count Enable inputs plus a Terminal Count output for ver-
satility in forming multistage counters. The CLK input is
active on the rising edge. Both PE and MR inputs are
active on low logic level. Presetting is synchronous to rising
edge of CLK and the Clear function of the VHC163 is syn-
chronous to CLK. Two enable inputs (ENP and ENT) and
Carry Output are provided to enable easy cascading of
counters, which facilitates easy implementation of n-bit
counters without using external gates.
Ordering Code:
Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

An input protection circuit insures that 0V to 7V can be
applied to the input pins without regard to the supply volt-
age. This device can be used to interface 5V to 3V systems
and two supply systems such as battery backup. This cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
