CD74HCT139 - Dual 2- to 4-Line Decoder/Demultiplexer

This page provides the datasheet information for the CD74HCT139, a member of the CD74HC139 Dual 2- to 4-Line Decoder/Demultiplexer family.

Datasheet Summary

Description

The ’HC139 and ’HCT139 devices contain two independent binary to one of four decoders each with a single active low enable input (1E or 2E).

Data on the select inputs (1A0 and 1A1 or 2A0 and 2A1) cause one of the four normally high outputs to go low.

Features

Multifunction Capability - Binary to 1 of 4 Decoders or 1 to 4 Line Demultiplexer.
Active Low Mutually Exclusive Outputs.
Fanout (Over Temperature Range) - Standard Outputs.
10 LSTTL Loads - Bus Driver Outputs.
. . . 15 LSTTL Loads.
Wide Operating Temperature Range . . . -55oC to 125oC.
Balanced Propagation Delay and Transition Times.
Signiﬁcant Power Reduction Compared to LSTTL Logic ICs.
