DATASHEET
IDTUS8031
Description
The IDTUS8031 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 IDTUS8031 is compatible
with the requirements of USB2.0 and features an extremely
low ON capacitance (C_ON) of 3.7 pF. The wide bandwidth of
this device (>720 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 IDTUS8031 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 (V_CC). 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
Features
• Low On capacitance, 3.7 pF (typical)
• Low On resistance, 6.5Ω (typical)
• Low power consumption (1 µA maximum)
– 10 µA maximum ICCT over and expanded control
voltage range (VIN=2.6 V, V_CC=4.3 V)
• Wide -3dB bandwidth, > 720 MHz
• 8K I/O to GND ESD protection
• Power OFF protection when V_CC= 0V, D+/D- pins can
tolerate up to 4.3 V
• Packaged in RoHS compliant 8-pin MSOP and 10-lead
µMLP (1.4 x1.8mm)
