GENERAL DESCRIPTION

The 74HC/HCT139 are high-speed Si-gate CMOS devices

and are pin compatible with low power Schottky TTL

(LSTTL). It is specified in compliance with JEDEC

standard no. 7A.

The 74HC/HCT139 are high-speed, dual 2-to-4 line

decoder/multiplexers. This device has two independent

decoders, each accepting two binary weighted inputs

(nA

LOW outputs (nY

LOW enable input (nE).

When nE is HIGH, every output is forced HIGH. The

enable can be used as the data input for a 1-to-4

demultiplexer application.

The “139” is identical to the HEF4556 of the HE4000B

family.
