MC54F353

DUAL 4-INPUT MULTIPLEXER WITH 3-STATE OUTPUTS The MC54/74F353 is a dual 4-input multiplexer with 3-state outputs. It can select two bits of data from four sources using common Select inputs. The outputs 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. Inverted Version of F253 Multifunction Capability Separate Enables for Each Multiplexer FUNCTIONAL DESCRIPTION The MC54/74F353 contains two identical 4-input multiplexers with 3-state outputs. They select two bits from four sources selected by common Select inputs (S0, S1).The 4-input multiplexers have individual Output enable (OEa, OEb) inputs which, when HIGH, force the outputs to a high impedance (high Z) state. The logic equations for the outputs are shown below: Za=OEa (I0a S1 S0 +I1a S1 S0 + I2a S1 S0 + I3a S1 S0) Zb=OEb (I0b S1 S0 + I1b S1...
