74F539
Dual 1-of-4 Decoder with 3-STATE Outputs
General Description
The 74F539 contains two independent decoders. Each
accepts two Address (A
them to select one of four mutually exclusive outputs. A
polarity control input (P) determines whether the outputs
are active HIGH (P
LOW input Enable (E) is available for data demultiplexing;
data is routed to the selected output in non-inverted form in
the active LOW mode or in inverted form in the active HIGH
mode. A HIGH signal on the active LOW Output Enable
(OE) input forces the 3-STATE outputs to the high imped-
ance state.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
