MAX4534CSD+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4534CSD+ is a single 4-to-1 fault-protected multiplexer manufactured by Analog Devices Inc. (Maxim Integrated). It operates with dual supplies from ±4.5V to ±20V or a single supply from +9V to +36V. The device features ±40V overvoltage protection when power is off and ±25V protection when power is on. Key electrical parameters include a maximum on-resistance of 400Ω, channel-to-channel matching of 10Ω max, and typical fault response time of 20ns. It is housed in a 14-pin Narrow SO package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected analog inputs handle signals exceeding supply rails without damage
• Rail-to-rail signal handling capability allows full voltage swing operation
• TTL/CMOS-compatible logic inputs ensure compatibility with standard digital interfaces
• No power-supply sequencing required for safe operation

Analog Switches, Multiplexers, Demultiplexers Applications

• Data-acquisition systems
• Industrial and process control
• Avionics signal routing
• Redundant/backup systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CSD corresponds to the 14-pin Narrow SOIC package and commercial temperature range (0°C to +70°C) before ordering. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing standards. Ensure the supplier provides valid traceability documentation for this Analog Devices part number.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4534CSD+ when a single 4-to-1 configuration is required rather than the dual 2-to-1 MAX4535 variant. Choose this part over other multiplexers if high-voltage fault protection up to ±40V is necessary during power-off states. Verify that the 400Ω maximum on-resistance meets the signal integrity requirements of the application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4534/MAX4535 family of fault-protected, high-voltage multiplexers. The MAX4534 specifically provides a single 4-to-1 switching configuration, while the MAX4535 offers dual 2-to-1 channels. Both share identical fault protection mechanisms and electrical characteristics, differing only in channel count and internal pin mapping.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4534ESD+ serves as a direct replacement offering the same functionality but with an extended industrial temperature range of -40°C to +85°C instead of the commercial 0°C to +70°C range. Other variants like MAX4534CPD provide the same electrical performance in a Plastic DIP package.
