MAX4513CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4513CSE is a quad, single-pole/single-throw (SPST) analog switch featuring fault protection and rail-to-rail signal handling. It contains 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 200Ω at +25°C and a maximum on-resistance match of 10Ω. Off-leakage current is specified at 0.5nA at +25°C and 10nA at +85°C. Turn-on time is typically 500ns and turn-off time is typically 400ns under standard test conditions.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected inputs allow NC_ and NO_ terminals to withstand overvoltage faults up to 36V during power-up or power-down without damage.
• Rail-to-Rail signal handling capability ensures unambiguous outputs by clamping the COM_ output to the appropriate supply voltage during fault conditions.
• Pin-compatible with industry-standard non-protected switches such as DG201, DG202, and DG213 for direct replacement in existing designs.
• TTL- and CMOS-compatible logic inputs ensure compatibility with standard digital logic levels when using ±15V or single +12V supplies.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' corresponds to the commercial temperature range (0°C to +70°C) and the 16-pin Narrow SOIC package configuration. Confirm that the component meets RoHS standards if required by the manufacturing process. Ensure the design accounts for the pinout compatibility with legacy parts while respecting the distinct fault-protection characteristics of the NC_ and NO_ pins compared to unprotected alternatives.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4513 variant specifically when a mix of normally closed and normally open switches is required within a single package. Consider this component for applications requiring high-voltage tolerance on signal lines without compromising signal integrity near the supply rails. Evaluate the 200Ω on-resistance limit against the load requirements to ensure acceptable voltage drop. Verify that the ±40V fault protection rating aligns with the maximum transient voltages present in the target circuit environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4513 belongs to the MAX4511/MAX4512/MAX4513 family of quad SPST analog switches manufactured by Analog Devices / Maxim Integrated. While the MAX4511 features four normally closed switches and the MAX4512 features four normally open switches, the MAX4513 uniquely combines two of each type. This family is designed to replace older non-fault-protected CMOS switches while providing enhanced robustness against overvoltage events on the signal paths.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitutes include the DG411, DG412, DG413, DG201, DG202, and DG213 due to pin compatibility. Note that these replacements lack the integrated fault protection and rail-to-rail capabilities of the MAX4513 series.
