MAX4632ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4632ESE+T 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. 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 maximum turn-on time of 150 ns. The NC_ and NO_ terminals are protected from overvoltage faults up to ±25V during operation and ±40V when powered off.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault protection for input terminals against overvoltage conditions

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature range. The '+T' designation indicates tape-and-reel packaging. Confirm availability status as distribution channels may list limited stock or discontinuation notices. Ensure the component meets RoHS compliance requirements for your assembly process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this model when dual SPDT switching with high-voltage fault protection is required. Verify that the ±25V fault protection limit aligns with system voltage spikes. Consider the 85 Ω on-resistance for signal integrity requirements. Ensure logic thresholds match the TTL/CMOS compatibility needs of the control interface.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX463x family of fault-protected analog switches. It shares pinouts with legacy non-fault-protected CMOS switches like the DG403. The 'E' suffix denotes an extended temperature range of -40°C to +85°C. The 'SE' indicates the 16-pin Narrow SOIC package configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the MAX4631 and MAX4633, though these offer different switch configurations (SPST and DPST respectively). Verify that the replacement part provides equivalent fault protection limits for the specific application environment.
