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).
