1-OF-8 DECODER
WITH 3-STATE OUTPUTS
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 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.
