MAX4906FELB+TG24

Analog Switches - Special Purpose Overview

The MAX4906FELB+TG24 is a high-speed USB 2.0 analog switch IC featuring two single-pole/double-throw (SPDT) channels. It operates on a single +3.0V to +3.6V supply with a maximum on-resistance of 7Ω and an on-capacitance of 69pF. The device includes +5.5V fault protection for COM terminals, ensuring compliance with USB 2.0 specifications. It supports data rates up to 480Mbps with a -3dB bandwidth of 1GHz. Quiescent current is 300µA maximum, reducing to less than 2µA in shutdown mode. The component is housed in a 10-pin µDFN package and functions within a temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Dual SPDT configuration optimized for high-performance USB 2.0 switching applications
• +5.5V overvoltage fault protection on analog inputs to prevent damage from bus shorts
• Low quiescent current with dedicated shutdown input for power conservation
• Compatible with low-voltage logic levels including 1.4V, 1.8V, and 3.3V

Analog Switches - Special Purpose Applications

• USB data line routing and host switching
• 10/100 Ethernet switching for docking stations
• Relay replacements in signal paths
• Bus switches for redundancy protection

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm tape-and-reel packaging details. Ensure the component matches the required pin configuration and thermal characteristics for the target PCB layout. Cross-reference the datasheet revision history to validate electrical parameter limits before finalizing procurement specifications.

Analog Switches - Special Purpose Selection Notes

Select this component when dual SPDT switching is required for USB 2.0 or Ethernet signals. The MAX4906F variant is necessary if +5.5V fault protection is needed to safeguard downstream circuitry. Compare on-resistance and capacitance values against other models in the series to ensure signal integrity requirements are met for the specific application frequency.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4906/MAX4907 family of high-speed analog switches designed by Analog Devices / Maxim Integrated. The 'F' designation indicates the inclusion of +5.5V fault protection features not present in the standard MAX4906 model. The 'L' suffix denotes the 10-pin µDFN package type, while 'E' specifies the industrial temperature rating.

Analog Switches - Special Purpose Replacement Considerations

The MAX4906ELB+T is a direct functional substitute lacking the +5.5V fault protection feature. The MAX4907FELB+T offers identical pinout but utilizes SPST switches instead of SPDT. Verify that the replacement part meets the specific voltage protection and channel configuration requirements of the original design.
