MAX4535ESD+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4535ESD+ is a dual 2-to-1 fault-protected multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates with ±4.5V to ±20V dual supplies or +9V to +36V single supply. The device features 400 Ω maximum on-resistance, matched between channels to 10 Ω maximum. It provides ±40V overvoltage protection with supplies off and ±25V protection with supplies on. Key electrical parameters include 275ns maximum turn-on time, 200ns maximum turn-off time, 1pC typical charge injection, and -53dB off-isolation at 1MHz. The component is housed in a 14-pin Narrow SOIC package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected inputs capable of handling signals up to ±40V beyond the supply rails when power is removed
• Rail-to-rail signal-handling capability allowing analog signals to pass through regardless of supply voltage levels
• TTL/CMOS-compatible logic inputs ensuring compatibility with standard digital logic families

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 ordering suffix 'ESD' corresponds to the 14-pin Narrow SOIC package and the industrial temperature grade (-40°C to +85°C). Confirm that the manufacturer designation matches Analog Devices Inc. or Maxim Integrated as indicated in official documentation. Ensure the component meets RoHS compliance standards required for your assembly process before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part for applications requiring high-voltage fault protection on analog inputs without power sequencing requirements. The dual 2-to-1 configuration is suitable for redundant signal paths. Verify that the 400 Ω on-resistance and 200ns switching speeds meet system timing constraints. Ensure the single-supply or dual-supply voltage ranges align with the available power rails in the target design.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4535 is part of the MAX4534/MAX4535 family of fault-protected, high-voltage multiplexers. While the MAX4534 offers a single 4-to-1 configuration, the MAX4535 provides two independent 2-to-1 switches in a single package. Both share identical fault-protection mechanisms and electrical characteristics, differing primarily in channel count and internal pin mapping.
