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 input (P)determines whether the outputs are active LOW or active HIGH. A HIGH Signal of the 74F538 on either of the active LOW Output Enable (OE ) inputs forces all outputs to the high imped-ance state. Two active HIGH and two active LOW input enables are available for easy expansion to 1-of 32 decod-ing with four packages, or for data demultiplexing to 1-of-8 or 1-of-16 destinations.
