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 Package Number Number FSA3259BQX 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.
