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 Ordering Code: Order Number FSA3259BQX Package Number MLP016E Package Description Pb-Free 16-Terminal Depopulated Quad Very-Thin Flat Pack No Leads (DQFN), JEDEC MO-241, 2.5 x 3.5mm Pb-Free package per JEDEC J-STD-020B.

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.
