MAX4520EUT+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4520EUT+T is a single-pole/single-throw (SPST) fault-protected analog switch in a 6-pin SOT-23 package. It features rail-to-rail signal handling and protects normally open terminals from overvoltage faults up to 36V during operation and 44V when powered off. The device operates with dual supplies of ±4.5V to ±20V or a single supply of +9V to +36V. Key electrical parameters include a maximum on-resistance of 160Ω, an off-leakage current of 0.5nA at +25°C, and a turn-on time of 500ns maximum. It supports TTL and CMOS logic inputs.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault protection for NC/NO pins up to ±36V with power applied and ±40V with power removed
• Rail-to-rail signal handling capability allowing signals to pass through the switch even if they exceed supply rails
• Low on-resistance of 160Ω maximum with parallel N-channel and P-channel FET construction
• TTL and CMOS compatible logic inputs ensuring compatibility across various supply voltages

Analog Switches, Multiplexers, Demultiplexers Applications

• Data Acquisition Systems
• Industrial and Process-Control Systems
• Avionics Equipment
• Automated Test Equipment (ATE)
• Redundant and Backup Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix '+T' indicates tape-and-reel packaging configuration. Confirm the 'E' designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure the component matches the 6-pin SOT-23 footprint requirements for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection on the signal path is required without compromising rail-to-rail output swing. It is suitable for applications needing low leakage current and high isolation. Consider the 160Ω on-resistance limit for signal integrity requirements. Verify that the input logic thresholds align with your system's control voltage levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4510/MAX4520 family of rail-to-rail, fault-protected SPST analog switches. The MAX4520 variant specifically provides a normally open configuration, whereas the MAX4510 offers a normally closed option. Both share identical pinouts and electrical characteristics except for the switch state relative to the logic input.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the same family include the MAX4510EUT+T for normally closed functionality. Other packages like the 8-pin µMAX (MAX4520EUA+) offer the same electrical performance but require different footprints. Ensure any replacement maintains the ±40V fault protection rating and SOT-23 form factor if space is constrained.
