MAX4510EUT+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4510EUT+T is a single-pole/single-throw (SPST) fault-protected analog switch in a 6-pin SOT23 package. It features rail-to-rail signal handling and protects NC/NO terminals from overvoltage faults up to 36V during operation and 44V when powered off. The device operates with dual supplies ranging from ±4.5V to ±20V or a single supply between +9V and +36V. Key electrical parameters include a maximum on-resistance of 160Ω, an off-leakage current of 0.5nA at +25°C, and a typical turn-on time of 175ns under dual supply conditions.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault protection for NC/NO terminals up to ±36V during power-on and ±40V with power removed
• Rail-to-rail signal handling capability ensuring unambiguous outputs during fault transitions
• Low off-leakage current of 0.5nA at +25°C
• TTL- and CMOS-compatible logic inputs without requiring power-supply sequencing

Analog Switches, Multiplexers, Demultiplexers Applications

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

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component matches the specific MAX4510 variant, as the MAX4520 shares identical pinouts but utilizes a normally open configuration instead of the MAX4510's normally closed design. Confirm the suffix indicates the -40°C to +85°C temperature range and the SOT23-6 package type. Ensure the ordering code includes the '+T' designation for tape-and-reel packaging if required by the assembly process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high-voltage fault tolerance is required on the signal path while maintaining low on-resistance within the supply rails. The MAX4510 is appropriate for applications needing normally closed behavior, whereas the MAX4520 should be chosen for normally open requirements. Consider the ±13mA clamp output current capability during fault conditions to ensure load compatibility. Verify that the COM pin does not require fault protection, as it lacks internal clamping diodes against overvoltage.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4510 belongs to the MAX4510/MAX4520 family of rail-to-rail, fault-protected SPST analog switches manufactured by Analog Devices / Maxim Integrated. This series distinguishes itself from traditional three-series-FET designs by using parallel FETs to achieve lower on-resistance and true rail-to-rail signal transmission. The EUT suffix specifically denotes the commercial-grade temperature range and the compact SOT23-6 surface-mount package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4520EUT+T: Functionally similar but configured as a Normally Open (NO) switch rather than Normally Closed (NC).

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4510 handle overvoltage faults on the NC terminal?

During a fault condition where the NC voltage exceeds the supply rails, the switch input becomes a high-impedance open circuit. The COM output is clamped to the appropriate supply voltage, sourcing or sinking up to 13mA to maintain the load voltage.

Is power-supply sequencing required for the MAX4510EUT+T?

No, the device does not require power-supply sequencing. It maintains fault protection even when power is removed, keeping the NC/NO terminals protected up to ±40V.

What is the difference between the MAX4510 and MAX4520?

The primary difference is the default switch state. The MAX4510 is a Normally Closed (NC) switch, meaning the signal path is connected when the logic input is low. The MAX4520 is a Normally Open (NO) switch, connecting the path when the logic input is high.
