TECHNICAL DATA

Dual 1-of-4 Decoder/Demultiplexer

High-Speed Silicon-Gate CMOS

KK74AC139

The KK74AC139 is identical in pinout to the LS/ALS139, HC/HCT139. The device inputs are compatible with

standard CMOS outputs; with pullup resistors, they are compatible with

LS/ALS outputs.

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.
