HD74AC538 - 1-of-8 Decoder

Description

The HD74AC538 decoder/demultiplexer accepts three Address (A0 to A2) input signal and decodes them to select one of eight mutually exclusive outputs.

A polarity control input (P) determines whether the outputs are active LOW or active HIGH.

Features

  • Output Polarity Control.
  • Data Demultiplexing Capability.
  • Multiple Enables for Expansion.

HD74AC538 1-of-8 Decoder with 3-State Output REJ03D0276–0200Z (Previous ADE-205-397 (Z)) Rev.2.00 Jul.16.2004 Description The HD74AC538 decoder/demultiplexer accepts three Address (A0 to A2) input signal and decodes them to select one of eight mutually exclusive outputs. A polarity control input (P) determines whether the outputs are active LOW or active HIGH. A HIGH signal on either of the active LOW output Enable (OE) inputs forces all outputs to the high impedance state. Two active HIGH and two active LOW input enables are available for easy expansion to 1-of-32 decoding with four packages, or for data demultiplexing to 1-of-8 or 1-of-16 destinations.
