Dual 1-of-4 Decoder/DemultiplexerThe 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 demultiplexing function is accomplished by
using the Address inputs to select the desired device output, and
utilizing the Select as a data input. By Integral Corp.
