The
KK
74HCT139A is identical in pinout to the LS/ALS139. The
KK
74HCT139A 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
Low Input Current: 1.0
