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 integrates two normally closed and two normally open switches within a 16-pin Narrow SO package. The device supports dual supplies from ±4.5V to ±18V or a single supply between +9V and +36V. Key electrical parameters include a maximum on-resistance of 250Ω and an on-resistance match of 200Ω between channels. Off-leakage current is specified at 0.5nA at +25°C and 10nA at +85°C. Turn-on time reaches a maximum of 1000ns, while turn-off time peaks at 900ns under single-supply conditions.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected inputs and outputs handle overvoltage faults up to 36V during operation and 40V when powered off.
• Rail-to-Rail signal handling 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.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE+' against the manufacturer's official documentation to confirm the commercial temperature range and lead-free status. Ensure the narrow SOIC package dimensions align with the target PCB footprint. Cross-reference the ordering information table in the datasheet to validate availability for the exact part number variant before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4513CSE+ when a mix of normally closed and normally open SPST switches is required within a single package. This component is suitable for designs needing high-voltage fault tolerance on the signal path. Verify that the logic input thresholds remain compatible with the system's control voltage levels across the intended operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4511/MAX4512/MAX4513 family of quad SPST analog switches manufactured by Analog Devices Inc./Maxim Integrated. While pin-compatible with legacy parts like the DG201/DG202/DG213, this series introduces enhanced fault protection features not present in the older generations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitute part numbers include MAX4511CSE+ and MAX4512CSE+. These variants share identical pinouts and physical dimensions but differ in switch configuration: MAX4511 offers four normally closed switches, while MAX4512 provides four normally open switches.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the MAX4513 handle fault conditions on its NC_ and NO_ terminals?

During a fault condition where the signal exceeds the supply rails, the NC_ or NO_ terminal becomes a high-impedance open circuit. Simultaneously, the COM_ output is clamped to the appropriate polarity supply voltage, sourcing or sinking up to 10mA to maintain the load voltage.

Are the COM_ pins fault protected?

No, the COM_ pins are not fault protected. They act as standard CMOS switch pins. Signals exceeding V+ or V- on the COM_ pin will trigger internal ESD diodes, potentially causing damage if current limits are exceeded.

What is the break-before-make behavior of the MAX4513?

The MAX4513 includes a break-before-make interval delay. When switching states, the existing connection opens before the new one closes, preventing momentary short circuits between the common and the new terminal.
