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 Fairchild_questions@onsemi.com.

FSA2147 — Low-Voltage, DPST Analog Switch with
Negative Signal Capability and Built-in Termination
to Eliminate Pop
Features
Description
The FSA2147 is a Double-Pole, Single Throw (DPST)
switch. The audio path defaults to audio mute and is
enabled with /OE. The FSA2147 includes a power-off
feature on the common port when VCC=0V to guarantee
signal isolation.
Built-In Termination on Unselected Audio Paths
Inhibits Audio Pop
6pF Typical Switch Off Capacitance
2.5Ω Typical On Resistance

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.

Notes:
2. On resistance is determined by the voltage drop between the A and B pins at the indicated current through the switch.
3. ∆ RON = RON max – RON min measured at identical VCC, temperature, and voltage.
4. Flatness is defined as the difference between the maximum and minimum values of on resistance over the
specified range of conditions.
