74F538
1-of-8 Decoder with 3-STATE Outputs
General Description
The 74F538 decoder/demultiplexer accepts three Address
(A
0
–A
2
) 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 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.
