SN54HC138J - 3-LINE TO 8-LINE DECODERS/DEMULTIPLEXERS

Download the SN54HC138J datasheet PDF. This datasheet also covers the SN54HC138 variant, as both devices belong to the same 3-line to 8-line decoders/demultiplexers family and are provided as variant models within a single manufacturer datasheet.

General Description

The SNx4HC138 devices are designed to be used in high-performance memory-decoding or data-routing applications requiring very short propagation delay times.

In high-performance memory systems, these decoders can be used to minimize the effects of system decoding.

Key Features

  • Targeted Specifically for High-Speed Memory Decoders and Data-Transmission Systems.
  • Wide Operating Voltage Range (2 V to 6 V).
  • Outputs Can Drive Up To 10 LSTTL Loads.
  • Low Power Consumption, 80-µA Maximum ICC.
  • Typical tpd = 15 ns.
  • ±4-mA Output Drive at 5 V.
  • Low Input Current of 1-µA Maximum.
  • Active Low Outputs ( Selected Output is Low).
  • Incorporate Three Enable Inputs to Simplify Cascading or Data Reception 2 Applic.
