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 Semiconductor’s 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

Description
The FSA2259 is a high-performance, dual, Single Pole
Double Throw (SPDT) analog switch that features low
R
ON
of 0.8Ω (typical) at 3.0V V
CC
. The FSA2259 operates
over a wide V
CC
range of 1.65V to 4.4V and is designed
for break-before-make operation. The select input is TTL-
level compatible.
The FSA2259 features very low quiescent current even
when the control voltage is lower than the V
CC
supply.
This feature suits mobile handset applications by
allowing direct interface with baseband processor
general-purpose I/Os with minimal battery consumption.
