MAX4534CUD+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4534CUD+T is a single 4-to-1 fault-protected multiplexer in a 14-pin TSSOP package. It operates with ±4.5V to ±20V dual supplies or +9V to +36V single supply. The device features rail-to-rail signal handling and overvoltage clamping at 150mV beyond the rails. On-resistance is 400 Ω max, matched between channels to 10 Ω max. All digital inputs have TTL logic thresholds for compatibility with single +12V or dual ±15V supplies.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault protection on NO_ pins allows signals up to ±40V when power is off and ±25V when supplies are active.
• Rail-to-rail analog signal handling capability with output clamping during fault conditions.
• No power-supply sequencing required; all channels turn off automatically when power is removed.

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 ordering suffix '+T' indicates tape-and-reel packaging rather than tube. Confirm the 'C' temperature grade corresponds to the commercial range of 0°C to +70°C. Ensure the manufacturer designation matches Analog Devices Inc./Maxim Integrated specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring high-voltage fault tolerance without power sequencing. Verify that the 400 Ω maximum on-resistance meets system loss requirements. Ensure the 14-TSSOP footprint aligns with the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4534/MAX4535 family of fault-protected multiplexers. The MAX4534 provides a single 4-to-1 configuration, while the MAX4535 offers dual 2-to-1 configurations. Both share identical electrical characteristics and pinouts for their respective channel counts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacement options include other variants within the MAX4534 series such as MAX4534EUD+ for extended temperature ranges. Verify package compatibility and thermal performance when substituting across different temperature grades.
