1 December 2013 FSA4159 Low-Voltage, 1Ω SPDT Analog Switch with Power-Off Isolation Features Low I CC When the S Input is Lower Than V CC Power-Off Isolation (V CC=0 V) 1 Ω On Resistance (R ON) for 4.5 V V CC 0.25 Ω Maximum R ON Flatness for 4.5 V V CC Space-Saving, Pb-Free, 6-Lead SC70 Surface Mount Package Broad V CC Operating Range: 1.65 V to 5.50 V Fast Turn-On and Turn-Of Times Break-Before-Make Enable Circuitry Pb-Free Green Packaging Description The FSA4159 is a high-performance Single-Pole / Double-Throw (SPDT) analog switch. The device features ultra-low R ON of 1 at 4. 5V V CC and operates over the wide V CC range of 1.65 V to 5.50 V. The device is fabricated with sub-micron CMOS technology to achieve fast switching speeds and is designed for break-before-make operation. The FSA4159 features very low quiescent current even when the control voltage is lower than the V CC supply. This feature services mobile handset applications by allowing direct interface with baseband processor general-purpose I/Os.

3 Absolute Maximum Ratings Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Symbol Parameter Min. Max.
