M54HC390 - DUAL DECADE COUNTER

Datasheet Summary

Description

The M54/74HC390 is a high speed CMOS DUAL DECADE COUNTER fabricated in silicon gate C2MOS technology.

It has the same high speed performance of LSTTL combined with true CMOS low power consumption.

This dual decade counter contains two independent ripple carry counters.
