1-of-8 Decoder/DemultiplexerThe 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
active-lot outputs. This device features three Chip Select inputs, two
active-low and one active-high to facilitate the demultiplexing,
cascading, and chip-selecting 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. By Integral Corp.
