Overview

SL74HCT138 1- of-8 Decoder/Demultiplexer High-Performance Silicon-Gate CMOS The SL74HCT138 is identical in pinout to the LS/ALS138.
The SL74HCT138 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
The SL74HCT138 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.
• 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.
