1 0.4: Low Voltage Dual DPDT Analog Switch General Description The FSA2467 is a Dual Double Pole Double Throw (DPDT) analog switch. The FSA2467 operates from a single 1.65V to 4.3V supply. The FSA2467 features an ultra-low On Resistance of 0.4: at a +2.7V supply and 25qC. This device is fabricated with sub-micron CMOS technology to achieve fast switching speeds and is designed for break-before-make operation. FSA2467 features very low quiescent current even when the control voltage is lower than the V CC supply. This feature services the mobile handset applications very well allowing for the direct interface with baseband processor general purpose I/Os.

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.
