Industry leading advantages include a propagation delay of less than 250ps, resulting from its low channel resistance and I/O capacitance. The device multiplexes differential outputs from a USB Host device to one of two corresponding outputs. The switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. It is designed for low bit-to-bit skew, high channel-to-channel noise isolation and is compatible with various standards, such as High Speed USB 2.0 (480 Mb/s). The PI3USB42 offers overvoltage protection per the USB2.0 specification. With the chip powered on or off, all I/O pins can withstand a short to Vbus (5V +/-10%). If VDD=0V, the I/Os can still have signals present, and the signal will NOT leak through to VDD. Functional Block Diagram D- SEL D-A D-B D+ /OE D+A D+B LOGIC Pin Assignment

Measured by the voltage drop between D and Dn pin at indicated current through the Switch On-Resistance is determined by the lower of the voltages on the two (D, Dn) pins. Note: Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed.

For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Guaranteed by design. 3. The switch contributes no propagational delay other than the RC delay of the On-Resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.25ns for 10pF load. Since this time constant is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the switch when used in a system is determined by the driving circuit on the driving side of the switch and its interactions with the load on the driven side.

For example, given a +3.3V supply, the output enables or select pins may be driven to low to 0V and high to 4.3V. Power Supply Sequencing Proper power supply sequencing is recommended for all CMOS devices. Always apply VDD and GND before applying signals to input/output or control pin.
