IN74HC138A - 3-8 Decoder/Demultiplexer

IK Semiconductor

Datasheet Details

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.
Outputs Directly Interface to CMOS, NMOS, and TTL.
Operating Voltage Range: 2.0 to 6.0 V.
Low Input Current: 1.0 µA.
