MAX4511CSE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4511CSE+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 NC_ terminals with fault protection up to ±36V during power-on and ±40V when powered off. On-resistance is typically 175Ω max at ±15V supplies, with channel matching of 10Ω max. Off-leakage current is 0.5nA at +25°C. Digital inputs are TTL- and CMOS-compatible.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected NO_ and NC_ terminals handle overvoltage faults up to 36V during operation and 40V when powered down.
• 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.
• Low power consumption with less than 2mW dissipation and no power-supply sequencing required.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' indicates the commercial temperature range and narrow SOIC package. Confirm RoHS compliance status via official documentation. Check for obsolescence or lifecycle changes directly with Analog Devices. Ensure pinout compatibility with legacy designs referencing DG201/DG202/DG213 standards before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring high-voltage fault tolerance on analog signals. Verify that the COM_ pins do not require fault protection, as they lack internal clamping. Ensure supply voltages remain within the specified ±4.5V to ±18V dual or +9V to +36V single ranges. Consider thermal derating if operating near maximum junction temperatures.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4511/MAX4512/MAX4513 family of quad SPST analog switches. The MAX4511 variant specifically features four normally closed switches. It serves as a direct replacement for older non-fault-protected CMOS switches while adding robust overvoltage protection capabilities to the signal paths.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitutes include MAX4512CSE+T and MAX4513CSE+T from the same family. These parts share identical pinouts and electrical characteristics but differ in switch configuration (Normally Open vs. Mixed). Verify logic state requirements before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

Are the COM_ pins fault protected?

No, the COM_ pins are not fault protected. Signals exceeding V+ or V- on these pins are clamped by internal ESD diodes, which may conduct heavily if limits are exceeded.

What is the behavior of the switch output during a fault condition?

During a fault, the NO_ or NC_ terminal becomes an open circuit. The switch output (COM_) furnishes up to 10mA of the appropriate polarity supply voltage to the load, ensuring rail-to-rail outputs.

How does the device handle power removal regarding fault protection?

Fault protection remains active when power is removed. The NO_ or NC_ terminals act as a virtual open circuit, capable of withstanding faults up to ±40V.
