Description

The 74F538 decoder/demultiplexer accepts three address (A0 - A2) input signals and decodes them to select one of eight mutually exclusive outputs. A Polarity control (P) input determines whether the outputs are active Low or active High. The 74F538 has 3-State outputs, and a High signal on the Output Enables (OE n) inputs will force all outputs to the high impedance state. Two active High (E2,E3) and two active Low (E 0, E 1) inputs 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.
