MAX4513ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4513ESE+T is a quad, single-pole/single-throw (SPST) analog switch featuring fault protection and rail-to-rail signal handling. It integrates two normally closed and two normally open switches within a 16-pin Narrow SO package. The device operates with dual supplies from ±4.5V to ±18V or a single supply between +9V and +36V. Key electrical parameters include a maximum on-resistance of 175Ω, an on-resistance match of 10Ω, and off-leakage current of 0.5nA at +25°C. Fault protection extends to ±36V during operation and ±40V when powered off.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected inputs and outputs handle overvoltage conditions up to 36V while powered and 40V when unpowered.
• Rail-to-Rail signal capability ensures unambiguous output transitions without glitching during fault events.
• Pin-compatible with industry-standard non-protected CMOS switches such as the DG411/DG412/DG413 series.
• Logic inputs are compatible with both TTL and CMOS standards across specified supply voltage ranges.

• Redundant/Backup Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' for the -40°C to +85°C industrial temperature range and 'SE' for the Narrow SO package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure power supply rails remain within the specified operational limits to maintain fault protection integrity.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4513 variant specifically for applications requiring a mixed configuration of two normally closed and two normally open channels. Verify that the load impedance and fault currents do not exceed the absolute maximum ratings for the COM_ pins. Consider the break-before-make timing characteristics if sequential switching is required in the circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX451x family of quad SPST analog switches manufactured by Analog Devices / Maxim Integrated. The MAX4513 distinguishes itself from the MAX4511 (all NC) and MAX4512 (all NO) by providing a hybrid configuration of two normally closed and two normally open switches within the same footprint.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4513ESE+T is pin-compatible with the DG413. Direct replacement requires verifying that the existing circuit does not rely on the lack of fault protection found in standard CMOS switches.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4513 behave during a fault condition?

During a fault where the NO_ or NC_ terminal exceeds the supply rails, the switch input becomes high impedance. The COM_ output is clamped to the appropriate supply voltage, sourcing or sinking up to 10mA to the load without transition glitches.

What is the break-before-make time delay for the MAX4513?

The MAX4513 features a break-before-make time delay ranging from 50ns to 100ns at +25°C, ensuring one channel turns off before another turns on.

Are the COM_ pins fault protected?

No, the COM_ and IN_ pins are not fault protected. Signals exceeding V+ or V- on these pins are clamped by internal ESD diodes, which may conduct heavily if limits are exceeded.
