MC74HC138A Datasheet 1-of-8 Decoder/demultiplexer

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: .. MOTOROLA SEMICONDUCTOR TECHNICAL DATA 1-of-8 Decoder/Demultiplexer High–Performance Silicon–Gate CMOS The MC54/74HC138A is identical in pinout to the LS138. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LSTTL outputs. The HC138A decodes a three–bit Address to one–of–eight active–low outputs.

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.
  • Output Drive Capability: 10 LSTTL Loads.
  • Outputs Directly Interface to CMOS, NMOS and TTL.
  • Op.
