MOTOROLA MC74F537DW

MC54/74F537
1-OF-10 DECODER
WITH 3-STATE OUTPUTS
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 forces all outputs to the high impedance state. Two input enables,
active HIGH E2 and active LOW E1, are available for demultiplexing data to
the selected output in either non-inverted or inverted form. Input codes greater
than BCD nine cause all outputs to go to the inactive state (i.e., same polarity
as the P input).
