MAX4632ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4632ESE 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 supplies from ±4.5V to ±18V or a single supply between +9V and +36V. Key electrical parameters include a maximum on-resistance of 85 Ω at +25°C, an off-leakage current of 0.5nA at +25°C, and a turn-on time of 150ns. The NO_ and NC_ terminals are protected from overvoltage faults up to ±25V during power-up or power-down.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault protection for NO_ and NC_ terminals against overvoltage conditions
• Rail-to-Rail signal handling without requiring power-supply sequencing
• TTL- and CMOS-logic compatible digital inputs
• Pin-compatible replacement for industry-standard DG401/DG403/DG405 devices

Analog Switches, Multiplexers, Demultiplexers Applications

• Automated Test Equipment (ATE)

• Industrial and Process Control Systems
• Avionics Applications
• Redundant/Backup Systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the -40°C to +85°C operating temperature range. Confirm the package type matches the design requirements. Check for RoHS compliance status as indicated in official documentation. Ensure the component source is authorized to avoid counterfeit parts.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this model when dual SPDT switching with fault protection is required. Verify that the ±25V fault protection limit meets the application's voltage stress requirements. Consider the 85 Ω on-resistance for signal integrity. Ensure the logic input thresholds align with the system's control voltage levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4632ESE belongs to the MAX4631/MAX4632/MAX4633 family of fault-protected, high-voltage dual analog switches. These devices upgrade existing industry-standard components by adding fault protection while maintaining pin compatibility. The family includes SPST (MAX4631), SPDT (MAX4632), and DPST (MAX4633) configurations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the MAX4631ESE and MAX4633ESE within the same series. Legacy equivalents such as the DG401, DG403, and DG405 can be replaced, though care must be taken regarding the lack of fault protection in those older devices.
