IN74ACT139 Datasheet (IK Semiconductor) - Dual 2-4 Decoder/Demultiplexer

IN74ACT139, Dual 2-4 Decoder/Demultiplexer

TECHNICAL DATA IN74ACT139 Dual 1-of-4 Decoder/Demultiplexer High-Speed Silicon-Gate CMOS The IN74ACT139 is identical in pinout to the LS/ALS139, HC/HCT139.

The IN74ACT139 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 demul
