Synchronous Presettable BCD Decade Counters

General Description

Features

Synchronous counting and loading

The ’LS160 and ’LS162 are high speed synchronous dec-

ade counters operating in the BCD (8421) sequence. They

are synchronously presettable for application in programma-

ble dividers and have two types of Count Enable inputs plus

a Terminal Count output for versatility in forming synchro-

nous multistage counters. The ’LS160 has an asynchronous

Master Reset input that overrides all other inputs and forces

the outputs LOW. The ’LS162 has a Synchronous Reset

input that overrides counting and parallel loading and allows

all outputs to be simultaneously reset on the rising edge of

the clock.

High speed synchronous expansion

Typical count rate of 35 MHz

Fully edge triggered
