MAX4513EPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4513EPE is a quad, single-pole/single-throw (SPST) analog switch featuring fault protection on normally open and normally closed terminals. It operates with dual supplies from ±4.5V to ±18V or a single supply between +9V and +36V. The device provides rail-to-rail signal handling with an on-resistance of 175Ω maximum at ±15V supplies. During fault conditions up to ±36V with power applied, the output clamps to the appropriate supply voltage while sourcing up to 10mA. Off-leakage current is 0.5nA at +25°C. The E-grade version supports temperatures from -40°C to +85°C in a 16-pin Plastic DIP package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected inputs handle overvoltage faults up to ±36V during operation and ±40V when powered off.
• Rail-to-Rail signal handling capability ensures unambiguous outputs during fault transitions.
• Pin-compatible with industry-standard non-protected switches such as DG201/DG202/DG213.
• TTL- and CMOS-compatible logic inputs require no power-supply sequencing.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EPE' corresponds to the extended temperature range (-40°C to +85°C) and the 16-pin Plastic DIP package configuration. Confirm that the application requires the mixed NO/NC channel configuration unique to the MAX4513 variant rather than the all-NO or all-NC alternatives within the family.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for circuits requiring robust fault protection on signal lines without sacrificing rail-to-rail signal swing. Ensure the load impedance does not exceed the 10mA output current limit during fault conditions. Verify that the required on-resistance match and leakage specifications align with the electrical characteristics provided for the E-grade temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4511/MAX4512/MAX4513 family of quad SPST analog switches. The MAX4513 specifically combines two normally closed and two normally open switches, distinguishing it from the MAX4511 (all NC) and MAX4512 (all NO). All variants share identical pinouts and fault-protection architectures.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include other MAX4513 variants with different packages (e.g., MAX4513ESE for SOIC, MAX4513EUE for TSSOP) or industrial grade versions (MAX4513CPE). Non-fault-protected equivalents like the DG201 series are pin-compatible but lack the overvoltage protection features.

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 by approximately 50mV, the input pin becomes high impedance. The COM_ output clamps to the appropriate supply voltage and can source or sink up to 10mA to the load.

Are the COM_ pins fault protected?

No, the COM_ and IN_ pins are not fault protected. Signals on these pins exceeding V+ or V- are clamped by internal diodes, and forward current must be limited to the maximum rating.

What is the break-before-make time delay?

The MAX4513 includes a break-before-make interval typical of 50ns to 100ns, which prevents shorting between the normally open and normally closed channels during switching.
