DATASHEET
LOW POWER DUAL SPDT HI-SPEED USB 2.0 (480MBPS) SWITCH
IDTUS8030
Description
The IDTUS8030 is a low power, dual SPDT 2-port hi-speed
USB 2.0 switch. This part is configured as a single pole,
double 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 IDTUS8030 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.
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 an expanded control
voltage range (VIN=2.6 V, V
CC
=4.3 V)
•
•
•
•
Wide -3dB bandwidth, > 850 MHz
Bi-directional operation
8 kV ESD protection
Packaged in RoHS compliant 10-lead µMLP (1.4
x1.8mm)
Applications
•
Notebooks, PDAs
•
Cellular phones, Digital cameras
•
LCD monitors, TVs, Set-top Boxes
•
Industrial temperature range (-40 to +85°C)

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the IDTUS8030. 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.
