Datasheet	HD74AC538 Datasheet

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.
