74F537
1-of-10 Decoder with 3-STATE Outputs
General Description
The 74F537 is one-of-ten decoder/demultiplexer with four
active HIGH BCD inputs and ten mutually exclusive out-
puts. A polarity control input determines whether the out-
puts are active LOW or active HIGH. The 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).
