MAX4907ELA+

Analog Switches - Special Purpose Overview

The MAX4907ELA+ is a dual single-pole/single-throw (SPST) analog switch designed for USB 2.0 high-speed applications at 480Mbps. It operates from a single +3.0V to +3.6V supply with a maximum on-resistance of 7Ω and an on-capacitance of 7pF. The device features a -3dB bandwidth of 1GHz, bit-to-bit skew of ≤100ps, and a shutdown input reducing quiescent current to <2µA. Logic compatibility includes 3.3V, 1.8V, and 1.4V levels. It is housed in an 8-pin µDFN package and operates over a temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Dual SPST configuration optimized for high-speed data routing
• Low on-resistance and on-capacitance for minimal signal distortion
• Integrated shutdown mode for significant power reduction
• Compatible with low-voltage logic inputs

Analog Switches - Special Purpose Applications

• USB 2.0 high-speed data line switching
• Switching between multiple USB hosts
• Sharing shared pins between different data types like SPI/GPIO
• Ethernet switching for 10/100 Base-T PHYs

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'ELA+' against the manufacturer's official documentation to confirm the exact pin-package code and fault protection status. Confirm that the component meets RoHS compliance requirements as specified in the datasheet before finalizing procurement specifications.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring dual independent SPST switching for USB or Ethernet signals. Ensure the design accommodates the +3.0V to +3.6V supply voltage range and utilizes the shutdown pin if low-power standby modes are required for the system architecture.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4906/MAX4907 family of high/full-speed USB 2.0 switches. While the MAX4906 offers dual SPDT configurations, the MAX4907 provides dual SPST switches. Both share similar electrical characteristics but differ in terminal availability and specific application routing capabilities within portable electronic devices.

Analog Switches - Special Purpose FAQ

Does the MAX4907ELA+ include overvoltage fault protection?

No, the MAX4907ELA+ does not feature +5.5V fault protection. This feature is available only in the MAX4907F variant.

What is the maximum operating supply voltage for this device?

The device is fully specified to operate from a single +3.0V to +3.6V power supply.

How does the shutdown input affect performance?

Driving the SHDN pin high reduces quiescent current to less than 2µA but limits the analog voltage range to 0 < V_ANALOG < 1.5V.
