74F253
Dual 4-Input Multiplexer with 3-STATE Outputs
General Description
The 74F253 is a dual 4-input multiplexer with 3-STATE out-
puts. It can select two bits of data from four sources using
common select inputs. The output may be individually
switched to a high impedance state with a HIGH on the
respective Output Enable (OE) inputs, allowing the outputs
to interface directly with bus oriented systems.
