MC74HCT138A Datasheet 1-of-8 Decoder/demultiplexer

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: MOTOROLA SEMICONDUCTOR TECHNICAL DATA 1-of-8 Decoder/Demultiplexer with LSTTL patible Inputs High–Performance Silicon–Gate CMOS The MC74HCT138A is identical in pinout to the LS138. The HCT138A may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The HCT138A decodes a three–bit Address to one–of–eight active–lot 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 TTL/NMOS Compatible I.
