| FSUSB11 Low Power High Bandwidth USB Switch Dual SPDT Multiplexer/Demultiplexer April 2004 Revised July 2004 FSUSB11 Low Power High Bandwidth USB Switch Dual SPDT Multiplexer/Demultiplexer General Description The FSUSB11 is a high performance Dual Single Pole Double Throw (SPDT) analog switch specially designed for the switching of both analog audio signal and USB 1.1 signals. The device features ultra low RON of 1.3 maximum at 4.5V VCC and 4.3 at 2.7V supply. High bandwidth and ultra low ON Resistance (RON) make this switch to be able to pass both USB low and full speed signal with minimum signal distortion. The device is fabricated with sub-micron CMOS technology to achieve fast switching speeds and is designed for break-before-make operation. The select input is TTL level compatible. Features s Space saving MicroPak packaging (1.6mm x 2.1mm) s USB 1.1 signal switching compliant s -3db bandwidth: >350MHz s Maximum 1.15 ON Resistance at 4.5V VCC and 4 for 2.7V supply s 0.3 maximum RON flatness for +5V supply s Broad VCC operating range: 1.65V to 5.5V s Fast turn-on and turn-off time s Break-before-make enable circuitry s Over-voltage tolerant TTL compatible control input Ordering Code: Product Order Number FSUSB11L10X Package Number MAC010A Code Top Mark ET 10-Lead MicroPak, 1.6 mm x 2.1mm 5K Units on Tape and Reel Package Description Supplied As Analog Symbols Truth Table Control Input(s) L H H = HIGH Logic Level L = LOW Logic Level Function D1 Connected to D+/D- D2 Connected to D+/D- Pin Descriptions Pin Names D, D1, D2 S Function Data Ports Control Input (Top Through View) MicroPak is a trademark of Fairchild Semiconductor Corporation.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 2: The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed. Note 3: Unused inputs must be held HIGH or LOW. They may not float.
