Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

FSUSB43 — Low-Power, Two-Port, High-Speed,
USB2.0 (480Mbps) Switch
Features
Description
Over-Voltage Tolerance (OVT) on all USB Ports
up to 5.25V without External Components
Low On Capacitance: 3.7pF Typical
The FSUSB43 is a bi-directional, low-power, two-port,
high-speed, USB2.0 switch. Configured as a doublepole, double-throw (DPDT) switch, it is optimized for
switching between two high-speed (480Mbps) sources
or a high-speed and full-speed (12Mbps) source.
Low On Resistance: 3.9Ω Typical
Low Power Consumption: 1μA Maximum
- 20μA Maximum ICCT over an Expanded Voltage
Range (VIN=1.8V, VCC=4.3V)
Wide -3db Bandwidth: > 720MHz
Packaged in 10-Lead MicroPak™ (1.6 x 2.1mm)
8kV ESD Rating, >16kV Power/GND ESD Rating
Power-Off Protection on All Ports when VCC=0V
- D+/D- Pins Tolerate up to 5.25V
Applications
Cell phone, PDA, Digital Camera, and Notebook
LCD Monitor, TV, and Set-Top Box
The FSUSB43 is compatible with the requirements of
USB2.0 and features an extremely low on capacitance
(CON) of 3.7pF. The wide bandwidth of this device
(720MHz) exceeds the bandwidth needed to pass the
third harmonic, resulting in signals with minimum edge
and phase distortion. Superior channel-to-channel
crosstalk also minimizes interference.
The FSUSB43 contains special circuitry on the switch
I/O pins for applications where the V CC supply is
powered-off (VCC=0), which allows the device to
withstand an over-voltage condition. This minimizes
current consumption even when the control voltage
applied to the SEL pin is lower than the supply voltage
(VCC). This feature is especially valuable to mobile
applications, such as cell phones, allowing for direct
interface with the general-purpose I/Os of the baseband
processor. Other applications include switching and
connector sharing in portable cell phones, PDAs, digital
cameras, printers, and notebook computers.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device
reliability. The absolute maximum ratings are stress ratings only.
