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.

email any questions regarding the system integration to

range of 1.65 V to 5.5 V. The
FSA1256A, FSA1257A, and FSA1258A operation range
is 2.7 V to 5.5 V. These devices are fabricated with sub-
micron CMOS technology to achieve fast switching
speeds and are designed for break-before-make
operation. The select input is TTL level compatible. The
FSA1256 and FSA1256A feature two Normally Open
(NO) switches. The FSA1257 and FSA1257A feature
two Normally Closed (NC) switches. The FSA1258 and
FSA1258A have one NO switch and one NC switch.
