Description

The MC54/74F537 is a one-of-ten decoder/demultiplexer with four active HIGH BCD inputs and ten mutually exclusive outputs. A polarity control input determines whether the outputs are active LOW or active HIGH. The MC54/74F537 has 3-state outputs, and a HIGH signal on the Output
Enable (OE ) input of MC74F537DW forces all outputs to the high impedance state. Two input enables,active HIGH E₂ and active LOWE ₁ , are available for demultiplexing data to the selected output in either non-inverted or inverted form. Input codes of MC74F537DW greater than BCD nine cause all outputs to go to the inactive state (i.e., same polarity as the P input).
