74AHCT138

3 TO 8 LINE DECODER DEMULTIPLEXER

Description

Pin Assignments

The 74AHCT138 is an advanced high speed CMOS device that is

designed to be pin compatable with 74LS low power Schottky types.

The device accepts a three bit binary weighted address on input pins

A0, A1 and A2 and when enabled will produce one active low output

with the remaining seven being high.

There are two active LOW enable inputs E1 and E2, and one active

HIGH enable input E3. The disabled device state results in all outputs

being high. The enable state occurs with E1 and E2 asserted low and

E3 asserted high.

The multiple enable lines allow for the parallel expansion of decoders

to create 4-to-16 line versions with no additional parts and 5-to-32

versions with the addition of a single inverter.

Features



Supply Voltage Range from 4.5V to 5.5V

Sinks or Sources 8mA at V_CC= 4.5V
