Overview

HD74AC538 1-of-8 Decoder with 3-State Output 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-of8 or 1-of-16 destinations.
Features • • • • Output Polarity Control Data Demultiplexing Capability Multiple Enables for Expansio...
