LOW POWER DUAL SPST HI-SPEED USB 2.0 (480MBPS) SWITCH

IDTUS8031

Description

Features

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, 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 =4.3 V)

low ON capacitance (C ) of 3.7 pF. The wide bandwidth of

• Wide -3dB bandwidth, > 720 MHz

• 8K I/O to GND ESD protection

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.

• Power OFF protection when V = 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)

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 ). 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
