Overview
TECHNICAL DATA IN74ACT138 1-of-8 Decoder/Demultiplexer High-Speed Silicon-Gate CMOS The IN74ACT138 is identical in pinout to the LS/ALS138, HC/HCT138.
The IN74ACT138 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
The IN74ACT138 decodes a three-bit Address to one-of-eight activelot outputs.
This device features three Chip Select inputs, two active-low and one active-high to facilitate the demultiplexing, cascading, and chipselecting functions.
The demultiplexing function is accomplished by using the Address inputs to select the desired device output; one of the Chip Selects is used as a data input while the other Chip Selects are held in their active states.
