FSA3259 Dual SP3T Analog Switch
November 2005 Revised December 2005
FSA3259 Dual SP3T Analog Switch
General Description
The FSA3259 Dual Single Pole Triple Throw (SP3T) analog switch operates from a single 1.65V to 5.5V supply. It features a typical On Resistance (RON) of 9: at a 3.3V supply and 25qC. The device is fabricated with sub-micron CMOS technology to achieve fast switching speeds and is designed for breakbefore-make operation. The FSA3259 also features wide-bandwidth (!250Mbz), high Off Isolation and low crosstalk. The dual SP3T configuration allows for maximum design flexibility.
Features O 9: typical On Resistance (RON) @ 3.3V O Ideal for 3:1 Multiplex/Demultiplex cell phone applications O Broad VCC operating range: 1.65V to 5.5V O 250MHz - 3dB Bandwidth O Break-before-make enable circuitry Applications O Cell phone, PDA O Video O Multi-port USB

Note 1: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. 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 rating. The Recommended Operating Conditions tables 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 control inputs must be held HIGH or LOW. They may not float.
