MAX4512ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4512ESE+ 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 housed in a 16-pin Narrow SO package. On-resistance is typically 175Ω max at ±15V supplies, with channel matching up to 10Ω max. Off-leakage current is 0.5nA at +25°C and 10nA at +85°C. Logic inputs are compatible with TTL and CMOS standards.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

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

• Redundant/Backup Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' confirms the -40°C to +85°C industrial temperature range and 'SE' indicates the 16-pin Narrow SOIC package. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure logic thresholds align with system voltage levels, particularly at higher supply voltages where TTL compatibility may vary.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection on signal lines is required alongside standard SPST switching functionality. The MAX4512 specifically offers four normally open switches, distinguishing it from the MAX4511 (normally closed) and MAX4513 (mixed). Verify that the COM_ pins do not require fault protection, as they lack internal clamping against overvoltage relative to the supply rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4512 belongs to the MAX4511/MAX4512/MAX4513 family of quad, fault-protected analog switches manufactured by Analog Devices / Maxim Integrated. These devices utilize parallel FET construction to achieve low on-resistance while maintaining high impedance during fault conditions. The series replaces traditional three-series-FET designs that suffer from reduced signal swing near supply rails.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the non-fault-protected DG201, DG202, DG213, DG411, DG412, and DG413. When substituting these legacy parts, ensure the new application does not expose the COM_ pins to voltages exceeding the supply rails, as the replacement lacks the MAX4512's fault-protection circuitry.
