MAX4632CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4632CSE+ is a high-voltage, dual analog switch featuring fault-protected inputs and Rail-to-Rail signal handling capabilities. It contains two normally open/normally closed single-pole/double-throw (SPDT) switches housed in a 16-pin Narrow SO 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 85 Ω maximum at +25°C, with channel matching of 6Ω maximum. Off-leakage current is 0.5nA at +25°C. Fault protection allows NC_ and NO_ terminals to withstand up to ±25V during operation and ±40V when powered off.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected inputs safeguard against overvoltage faults up to specified limits during power-up or power-down sequences.
• Rail-to-Rail signal handling ensures unambiguous outputs by clamping the COM_ terminal to the appropriate supply voltage during fault conditions.
• TTL- and CMOS-logic compatible digital inputs simplify interface requirements across various supply voltages.

Analog Switches, Multiplexers, Demultiplexers Applications

• Automated Test Equipment
• Data Acquisition Systems
• Industrial and Process Control Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE+' corresponds to the commercial temperature range and narrow SOIC packaging. Confirm availability status as distribution channels may list limited stock or obsolete status for this component. Ensure the ordering information matches the required pin configuration and thermal specifications for the target application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4632CSE+ when dual SPDT switching with high-voltage fault protection is required. Verify that the ±25V on-state fault limit meets the system's transient voltage requirements. Consider the 85 Ω on-resistance and 150 ns turn-on time for signal integrity constraints. Ensure the logic thresholds align with the driving circuit's output levels at the chosen supply voltage.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4631/MAX4632/MAX4633 family of fault-protected analog switches. It serves as an upgrade to industry-standard DG401/DG403/DG405 devices, offering enhanced input protection while maintaining pin compatibility. The MAX4632 variant specifically provides SPDT functionality compared to the SPST MAX4631 or DPST MAX4633.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible replacements include the non-fault-protected DG403. Direct substitution requires verifying that the target application does not require the fault-protection features inherent to the MAX4632 series.
