74LVX163

Low Voltage Synchronous Binary Counter with

Synchronous Clear

facilitates easy implementation of n-bit counters without

using external gates.

General Description

The LVX163 is a 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 versatility in forming

multistage counters. The CLK input is active on the rising

edge. Both PE and MR inputs are active on low logic lev-

els. Presetting is synchronous to rising edge of the CLK

and the Clear function of the LVX163 is synchronous to the

CLK. Two enable inputs (CEP and CET) and Carry Output

are provided to enable easy cascading of counters, which

The inputs tolerate voltages up to 7V allowing the interface

of 5V systems to 3V systems.

Features

■ Input voltage level translation from 5V to 3V

■ Ideal for low power/low noise 3.3V applications

■ Guaranteed simultaneous switching noise and dynamic

threshold performance
