PI5C33X257 12 Channel, 2:1 Mux/DeMux Bus Switch PI5C33X257 12-Channel, 2:1 Mux/DeMux Bus Switch Features Description Near-Zero propagation delay The PI5C33X257 is a 12-channel, 2:1 multiplexer/demultiplexer with three-state outputs. Inputs can be connected to outputs with 5-ohm switches connect inputs to outputs low on resistance (5-ohm) with no additional ground bounce noise Direct bus connection when switches are ON or propagation delay. Ultra Low Quiescent Power (0.2A typical) Ideally suited for notebook applications Packaging (Pb-free & Green Available): 48-pin 150 mil wide plastic BQSOP (B) Logic Block Diagram Pin Configuration (1) Truth Table (2) (2) (2) (2) En Sn YA YB YC YD Function H X Hi-Z Hi-Z Hi-Z Hi-Z Disable L L IA0 IB0 IC0 ID0 S = 0 L H IA1 IB1 IC1 ID1 S = 1 Notes: 1.

For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Typical values are at Vcc = 5.0V, TA = 25C ambient and maximum loading. 3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second. 4. Measured by the voltage drop between I and Y pin at indicated current through the switch. ON resistance is determined by the lower of the volt- ages on the two (I,Y) pins.
