A product Line of Diodes Incorporated PI5C3257 Quad 2:1 Mux/DeMux Bus Switch Features: Description Near-Zero propagation delay The PI5C3257 is a Quad 2:1 multiplexer/demultiplexer with three-state outputs that is pinout and function compatible with 5 switches connect inputs to outputs the PI74FCT257T, 74F257, and 74ALS/AS/LS257. Inputs can Direct bus connection when switches are ON be connected to outputs with low On-Resistance (5) with no Ultra Low Quiescent Power (0.2A typical) additional ground bounce noise or propagation delay. Ideally suited for notebook applications Pin compatible with 74 series 257 logic devices Packaging (Pb-free & Green available): 16-pin 150-mil wide plastic QSOP (Q) 16-pin 150-mil wide plastic SOIC (W) 16-pin 173-mil wide plasticTSSOP (L) Block Diagram Pin Configuration IA0 IA1 IB0 IB1 IC0 IC1 ID0 ID1 S 16 V 1 CC IA0 15 E 2 IA1 3 14 ID0 E YA 4 13 ID1 IB0 12 YD 5 IB1 6 11 IC0 S YB 7 10 IC1 GND 8 9 YC YA YB YC YD (1) Truth Table Pin Description E S YA YB YC YD Function Pin Name Description H X Hi-Z Hi-Z Hi-Z Hi-Z Disable IAn-IDn Data Inputs L L IA0 IB0 IC0 ID0 S = 0 S Select Inputs L H IA1 IB1 IC1 ID1 S = 1 E Enable Note: YA-YD Data Outputs 1.
