TECHNICAL DATA

KK74ACT139

Dual 1-of-4 Decoder/Demultiplexer

High-Speed Silicon-Gate CMOS

The KK74ACT139 is identical in pinout to the LS/ALS139,

HC/HCT139. The KK74ACT139 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.
