DATASHEET LOW POWER DUAL SPST HI-SPEED USB 2.0 (480MBPS) SWITCH
IDTUS8032
Description
The IDTUS8032 is a low power, dual SPST 2-port hi-speed USB 2.0 switch. This part is configured as a single pole, single throw switch and is optimized for switching or isolating a hi-speed (480 Mbps) source or a hi-speed and full-speed (12 Mbps) source. The IDTUS8032 is compatible with the requirements of USB2.0 and features an extremely low ON capacitance (CON) of 6.0 pF. The wide bandwidth of this device (>500 MHz) exceeds the bandwidth needed to pass the 3rd harmonic, resulting in signals with minimum edge and phase distortion. Superior channel-to-channel crosstalk also minimizes interference. The IDTUS8032 contains circuitry on the D+/D- pins which allows the device to withstand an overvoltage condition. This device is also designed to minimize current consumption even when the control voltage applied to the OE pin is lower than the supply voltage (VCC). This feature is especially valuable to portable applications such as cell phones, allowing for direct interface with the general purpose I/Os of the baseband processor.
Features
* Low On capacitance, 4.5 pF (typical) * Low On resistance, 3.5 (typical) * Low power consumption (3 mA maximum)
- 1 mA typical ICCT over and expanded control voltage range (VIN=2.6 V, VCC=3.6 V)
* Wide -3dB bandwidth, > 500 MHz * 8K I/O to GND ESD protection * Power OFF protection when VCC= 0V, D+/D- pins can
tolerate up to 3.6 V
* Packaged in RoHS compliant 8-pin SOIC or 8-pin MSOP
Applications
* Notebooks, PDAs * Cellular phones, Digital cameras * LCD monitors, TVs, Set-top Boxes

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the IDTUS8032. These ratings, which are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range. All voltages referenced to ground.
