MAX4633ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4633ESE+ is a high-voltage, dual analog switch featuring fault-protected inputs and Rail-to-Rail signal handling capabilities. It contains two normally open double-pole/single-throw (DPST) switches housed in a 16-pin Narrow SOIC package. The device operates with dual power supplies ranging from ±4.5V to ±18V or a single supply between +9V and +36V. On-resistance is typically 62Ω at +25°C with ±15V supplies, while off-leakage current is limited to 0.5nA at +25°C. Fault protection allows NO_ and NC_ terminals to withstand overvoltage faults up to ±36V during operation and ±40V when powered down.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected NO_ and NC_ terminals safeguard connected loads from overvoltage conditions by clamping the COM_ output to the appropriate supply voltage.
• Rail-to-Rail signal handling ensures unambiguous outputs during fault transitions without requiring specific power-supply sequencing.
• TTL- and CMOS-compatible digital inputs allow direct interfacing with standard logic families across various supply voltages.

Analog Switches, Multiplexers, Demultiplexers Applications

• Automated Test Equipment (ATE)
• Data Acquisition Systems
• Industrial and Process Control Systems
• Avionics Applications
• Redundant/Backup Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range of -40°C to +85°C. Confirm the 'SE' designation corresponds to the 16-pin Narrow SOIC package. Ensure the '+' suffix confirms compliance with RoHS standards. Cross-reference the manufacturer's part number against official distributor catalogs to validate authenticity and current availability status before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4633ESE+ for applications requiring dual DPST switching with high-voltage fault tolerance. This component is suitable where signals may exceed supply rails, as it protects downstream circuitry. Consider the on-resistance match and leakage characteristics for precision analog paths. Verify that the required supply voltage range aligns with the ±4.5V to ±18V or +9V to +36V specifications.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4633 is part of the MAX4631/MAX4632/MAX4633 family of fault-protected analog switches. These devices are pin-compatible with industry-standard DG401/DG403/DG405 switches but offer enhanced protection features. The MAX4633 specifically provides two DPST switches, distinguishing it from the SPST (MAX4631) and SPDT (MAX4632) variants within the same series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4633ESE+ is pin-compatible with the DG405. However, verify that existing designs can accommodate the different internal structure and fault-protection behavior. Ensure that the replacement maintains the required fault voltage ratings and signal handling capabilities for the specific application environment.
