Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

Both Lower Than V CC devices feature ultra low R of 1.15 maximum at ON Maximum 1.15 On Resistance (R ) at 4.5 V V ON CC 4.5 V V and operates over the wide V range of CC CC 1.65 V to 5.5 V for FSA4157, and 2.7 V to 5.5 V for 0.3 Maximum R Flatness at 4.5 V V ON CC FSA4157A. The device is fabricated with sub-micron Space-Saving 6-lead, MicroPak and CMOS technology to achieve fast switching speeds and SC70 6 Packages is designed for break-before-make operation. The select input is TTL level compatible. Broad V Operating Range: CC FSA4157: 1.65 V to 5.5 V The FSA4157A features very low quiescent current even FSA4157A: 2.7 V to 5.5 V when the control voltage is lower than the V supply. CC This feature services the mobile handset applications Fast Turn-On and Turn-Off Time very well allowing for the direct interface with baseband Break-Before-Make Enable Circuitry processor general purpose I/Os.
