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

Applications

CMOS Low Power Consumption



Memory chip select decoding

Schmitt Trigger Action at All Inputs

Demultiplexing

Inputs Accept up to 6.0V

Single line peripheral control

ESD Protection Tested per JESD 22

Allow simple serial bit streams from a microcontroller to control as

many peripheral lines as needed

Exceeds 200-V Machine Model (A115-A)

Exceeds 2000-V Human Body Model (A114-A)

Exceeds 1000-V Charged Device Model (C101C)

Latch-Up Exceeds 250mA per JESD 78, Class II

Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)

Halogen and Antimony Free. “Green” Device (Note 3)

Notes:

1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.

2. See http://www.diodes.com for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free.

3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and

<1000ppm antimony compounds.
