Features, Applications

The 74F539 contains two independent 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 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.

HD74HCT640 : Octal Bus Transceivers ( With 3-state Outputs ). Both the HD74HCT640 and the HD74HCT643 have one active low enable input (G and a direction control (DIR). When the DIR input is high, data flows from the A inputs to the B outputs. When DIR is low, data flows from to A. The HD74HCT640 transfers inverted data from one bus to the other. The HD74HCT643 transfers inverted data from the A bus to the B bus and non-inverted.
