DM7493A - Decade and Binary Counters

This page provides the datasheet information for the DM7493A, a member of the DM7490A Decade and Binary Counters family.

Datasheet Summary

Description

Each of these monolithic counters contains four masterslave flip-flops and additional gating to provide a divide-bytwo counter and a three-stage binary counter for which the count cycle length is divide-by-five for the 90A and divideby-eight for the 93A All of these counters have a gated zero reset

Features

Y Typical power dissipation 90A 145 m.
