EMULTIPLEXER
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 demultiplexing
function is accomplished by using the Address inputs to select the
desired device output, and utilizing the Select as a data input.
TTL/NMOS Compatible Input Levels
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 4.5 to 5.5 V
