Dual 1-of-4 Decoder/Demultiplexer

General Description

The ’AC/’ACT139 is a high-speed, dual 1-of-4 decoder/

demultiplexer. The device has two independent decoders,

each

accepting

two

inputs

and

providing

four

mutually-exclusive active-LOW outputs. Each decoder has

an active-LOW Enable input which can be used as a data in-

put for a 4-output demultiplexer. Each half of the ’AC/

’ACT139 can be used as a function generator providing all

four minterms of two variables.

Features

n ICC reduced by 50%

n Multifunction capability

n Two completely independent 1-of-4 decoders

n Active LOW mutually exclusive outputs

n Outputs source/sink 24 mA

n ’ACT139 has TTL-compatible inputs

n Standard Military Drawing (SMD)
