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.

This configuration enables audio and USB data to share a Audio: 3 Typical On Resistance common connector port. The architecture is designed to -3db Bandwidth: > 720MHz allow audio signals to swing below ground. This means a common USB and headphone jack can be used for Low Power Consumption personal media players and portable peripheral devices. Power-off Protection on Common D+/R, D-/L Ports Since USB2.0 is an industry standard for shared data- Automatically Detects V for Switch Path bus path in portable devices, the FSA221 also incorporates Selection a V detection capability. The FSA221 includes a bus power-off feature to minimize current consumption when Applications V is not present. This power-off circuitry is available bus for the common D+/R, D-/L ports only. Typical Cell Phone, PDA, Digital Camera, and Notebook applications involve switching in portables and consumer applications, such as cell phones, digital LCD Monitor, TV, and Set-Top Box cameras, and notebooks with hubs or controllers.
