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

FSUSB45 — High-Speed USB2.0 (480Mbps) Switch
with Dedicated Charger Port Detect
Features
Description
The FSUSB45 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 HS (480 Mbps) sources or an
HS source and a Full-Speed (12 Mbps) source.
Low On Capacitance: 7.0 pF Typical
Low On Resistance: 3.9 Ω Typical
Low Power Consumption: 1 μA Maximum
- 15 μA Maximum ICCT over an Expanded Voltage
Range (VIN=1.8 V, VCC=4.3 V)
Wide -3 db Bandwidth: > 720 MHz
Packaged in:
- 10-Lead MicroPak™ (1.6 x 2.1 mm)
- 10-Lead UMLP (1.4 x 1.8 mm)
8 kV ESD Rating, >16 kV Power/GND ESD Rating
Power-Off Protection on All Ports When VCC=0 V
- D+/D- Pins Tolerate up to 5.25 V
Applications
Cell Phone, PDA, Digital Camera, and Notebook
LCD Monitor, TV, and Set-Top Box
IMPORTANT NOTE:
For additional performance information, please contact
analogswitch@fairchildsemi.com.
The FSUSB45 is compatible with the requirements of
USB2.0 and features an extremely low on capacitance
(CON) of 7.0 pF. The wide bandwidth of this device
(720 MHz) 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 FSUSB45 contains special circuitry on the switch
I/O pins for applications where the VCC supply is
powered-off (VCC=0), which allows the device to
withstand an over-voltage condition. This device is
designed to minimize 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. An additional feature is
the detection of the 1,1 state on D+/D- to signal an
interrupt (INT) to the processor when entering a
dedicated charging port mode of operation.

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.
