DATASHEET
IDTUS8032
LOW POWER DUAL SPST HI-SPEED USB 2.0 (480MBPS) SWITCH
Description
Features
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.
• Low On capacitance, 4.5 pF (typical)
• Low On resistance, 3.5Ω (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
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.
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.
