IN74HCT138A

1-OF-8 DECODER/DEMULTIPLEXER

High-Performance Silicon-Gate CMOS

The IN74HCT138A is identical in pinout to the LS/ALS138.

The IN74HCT138A may be used as a level converter for

interfacing TTL or NMOS outputs to High Speed CMOS inputs.

The IN74HCT138A 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.

ORDERING INFORMATION

• 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 µA
