MAX4511ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4511ESE+T is a quad, single-pole/single-throw (SPST) analog switch featuring fault protection and rail-to-rail signal handling. It operates with dual supplies from ±4.5V to ±18V or a single supply between +9V and +36V. The device provides four separately controlled switches with an on-resistance of 175Ω max at ±15V supplies, matched within 10Ω max. Off-leakage current is 0.5nA at +25°C. Fault-protected terminals handle up to ±36V during power-on and ±40V when powered off. Logic inputs are TTL and CMOS compatible.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected NC_ and NO_ terminals withstand overvoltage faults up to ±36V during operation and ±40V when unpowered.
• Rail-to-Rail signal handling capability ensures unambiguous outputs during fault transitions without transition glitches.
• Pin-compatible with industry-standard non-protected switches such as DG201/DG202/DG213 and DG411/DG412/DG413.
• Low power consumption with less than 2mW dissipation and no requirement for power-supply sequencing.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range of -40°C to +85°C and 'SE' denotes the narrow SOIC package. Confirm the '+T' suffix corresponds to reel packaging if required by assembly equipment. Cross-reference the manufacturer's latest ordering guide to ensure the part number matches current production status and RoHS compliance requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection on the signal path is critical for system reliability. Ensure the application voltage does not exceed the ±36V operational limit or ±40V power-off limit on protected pins. Verify that the logic interface meets the specified thresholds for the chosen supply voltage. Consider the on-resistance match requirement if channel uniformity is essential for the signal path.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4511 variant specifically contains four normally closed (NC) switches. It belongs to the MAX4511/MAX4512/MAX4513 family, which shares identical pinouts but differs in switch configuration. The MAX4512 offers four normally open switches, while the MAX4513 combines two normally closed and two normally open switches within the same package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements include the MAX4512ESE+T and MAX4513ESE+T for functional equivalence with different switch states. Non-fault-protected equivalents like the DG201 or DG411 may fit physically but lack the overvoltage protection features.
