PI3USB14-A
Low Voltage, High Bandwidth, USB 2.0, 4:1 Mux/DeMux with Single Enable
Description
The PI3USB14-A is a 2-channel, 4:1 Multiplexer/Demultiplexer with 3-state outputs. The switch introduces no additional ground bounce noise or propagation delay. The PI3USB14-A device is very useful in switching USB 2.0 signals and others that have high bandwidth (-3dB BW is 815MHz).

Notes 1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VDD = 3.3V, TA = 25°C 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 Y and In pin at indicated current through the switch. On-Resistance is determined by the lower of the voltages on the two (Y, In) pins.
5. This parameter is determined by device characterization but is not production tested.
