IN74ACT139D

Manufacturer Part Number
IN74ACT139D
Description
Dual 1-of-4 decoder/demultiplexer high-speed silicon-gate CMOS
Manufacturer
Integral Corp.
Datasheet
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 4.5 to 5.5 V
• Low Input Current: 1.0 µA; 0.1 µA @ 25°C
• Outputs Source/Sink 24 mA
HC/HCT139. The IN74ACT139 may be used as a level converter
for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
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
The IN74ACT139 is identical in pinout to the LS/ALS139,
This device consists of two independent 1-of-4 decoders, each
