74VHC163

4-Bit Binary Counter with Synchronous Clear

An input protection circuit insures that 0V to 7V can be

General Description

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.

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.

Features

■ High speed: f_MAX= 185 MHz (typ) at V_CC= 5V

■ Low power dissipation: I_CC= 4 µA (max) at T_A= 25°C

■ Synchronous counting and loading

■ High-speed synchronous expansion

■ High noise immunity: V_NIH= V_NIL= 28% V_CC(min)

■ Power down protection is provided on all inputs.

■ Low noise: V_OLP= 0.8V (max)

■ Pin and function compatible with 74HC163
