MAX4511ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4511ESE+ is a quad, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices/Maxim Integrated. It features fault protection on the normally closed terminals, allowing operation with dual supplies from ±4.5V to ±18V or a single supply between +9V and +36V. The device operates within an extended temperature range of -40°C to +85°C and is housed in a 16-pin Narrow SO package. Key electrical specifications include a maximum on-resistance of 175Ω, an on-resistance match of 10Ω, and low off-leakage current of 0.5nA at +25°C. Logic inputs are compatible with both TTL and CMOS standards.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

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

Analog Switches, Multiplexers, Demultiplexers Applications

• ATE Equipment
• Data Acquisition Systems
• Industrial and Process-Control Systems
• Avionics
• Redundant/Backup Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix ESE corresponds to the -40°C to +85°C temperature grade and 16-pin Narrow SOIC package. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input logic levels align with the specified thresholds for the intended supply voltage configuration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring robust fault protection on switched signals without compromising rail-to-rail output swing. Consider the 175Ω maximum on-resistance and 500ns turn-off time for high-speed requirements. 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

This part belongs to the MAX4511/MAX4512/MAX4513 family of quad SPST analog switches. The MAX4511 variant specifically provides four normally closed switches. It serves as a direct pin-compatible upgrade for legacy non-fault-protected CMOS switches like the DG411 series, offering enhanced reliability in harsh electrical environments while maintaining standard footprint compatibility.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the DG201, DG202, and DG213 series. Note that these alternatives lack the integrated fault protection features found in the MAX4511. Designers must ensure that circuit layouts accommodate the specific fault-handling characteristics if substituting with non-protected devices.
