Dual 1-of-4 Decoder/Demultiplexer

General Description

Features

Multifunction capability

The ’F139 is a high-speed, dual 1-of-4 decoder/demultiplex-

er. The device has two independent decoders, each accept-

ing two inputs and providing four mutually exclusive active

LOW outputs. Each decoder has an active LOW Enable in-

put which can be used as a data input for a 4-output demul-

tiplexer. Each half of the ’F139 can be used as a function

generator providing all four minterms of two variables.

Two completely independent 1-of-4 decoders

Active LOW mutually exclusive outputs

Guaranteed 4000V minimum ESD protection
