IN74HC138A Datasheet 1-of-8 Decoder/demultiplexer High-performance Silicon-gate CMOS

Manufacturer: Unknown Manufacturer

Overview: TECHNICAL DATA IN74HC138A 1-of-8 Decoder/Demultiplexer High-Performance Silicon-Gate CMOS The IN74HC138A is identical in pinout to the LS/ALS138. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALSTTL outputs. The IN74HC138A decodes a three-bit Address to one-of-eight active-low outputs.

Description 1-of-8 Decoder/Demultiplexer High-Performance Silicon-Gate CMOS
Datasheet IN74HC138A_ETC.pdf

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