TECHNICAL DATA

IN74HCT139A

Dual 1-of-4 Decoder/Demultiplexer

High-Performance Silicon-Gate CMOS

The IN74HCT139A is identical in pinout to the LS/ALS139. The

IN74HCT139A may be used as a level converter for interfacing TTL or

NMOS outputs to High Speed CMOS inputs.

This device consists of two independent 1-of-4 decoders, each of

which decodes a two-bit Address to one-of-four active-low outputs.

Active-low Selects are provided to facilitate the demultiplexing and

cascading functions. The demultiplexing function is accomplished by

using the Address inputs to select the desired device output, and utilizing

the Select as a data input.
