HD74AC539規(guī)格書詳情
Description
The HD74AC539 contains two inpedendent decoders. Each accepts two Address (A0, A1) 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
