FSUSB74MPX

Analog Switches - Special Purpose Overview

The FSUSB74MPX is a 4:1 high-speed USB multiplexer and switch manufactured by onsemi. It integrates four differential data lines with a single enable control input to route signals from one of four sources to a common output. The device supports USB 2.0 specifications, providing low insertion loss and minimal signal distortion for high-frequency applications. It operates within a supply voltage range of 2.97 V to 3.63 V and functions across an ambient temperature range of -40°C to +85°C. The component is housed in a compact SC-70-14 surface-mount package, designed for space-constrained portable electronics.

Analog Switches - Special Purpose Feature Summary

• Supports high-speed data transmission compliant with USB 2.0 standards
• Features low power consumption suitable for battery-operated mobile devices

Analog Switches - Special Purpose Applications

• Mobile phones and smartphones for camera or peripheral switching
• Portable media players and MP3 devices
• Digital cameras and camcorders
• Personal digital assistants (PDAs)

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'MPX' corresponds to the SC-70-14 tape and reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the component meets the required operating temperature range for the intended application environment.

Analog Switches - Special Purpose Selection Notes

Select this component when a compact solution is needed to switch between multiple USB peripherals or internal modules in mobile designs. Compare against similar parts like the FSUSB73 if only three channels are required. Verify that the SC-70-14 package dimensions fit the PCB layout constraints. Check electrical parameters such as insertion loss and bandwidth against the specific USB signal integrity requirements of the design.

Analog Switches - Special Purpose Part Context

The FSUSB74MPX belongs to the FSUSB series of high-speed USB switches from onsemi, formerly Fairchild Semiconductor. This series is widely used in consumer electronics for managing multiple USB connections. The MPX suffix typically denotes the specific tape and reel packaging variant, distinguishing it from tube-packaged versions like the FSUSB74M.

Analog Switches - Special Purpose Replacement Considerations

The FSUSB74MTCX is a direct functional equivalent with identical electrical characteristics but may differ in packaging type. Other compatible alternatives include the FSUSB73 for 3-channel applications or the FSUSB63 for 3:1 configurations. Always verify pinout compatibility and package dimensions before substituting.
