HD74AC539
Dual 1-of-4 Decoder with 3-State Output
Description
The HD74AC539 contains two inpedendent decoders. Each accepts two Address (A
0
, A
1
) input signals and
decodes them to select one of four mutually exclusive outputs. A polarity control input (P) determines
whether the outputs are active HIGH (P = L) or active LOW (P = H). An active 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 impedance state.
Feature
Outputs Source/Sink 24 mA
