MAX4632EPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4632EPE 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 Plastic DIP 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 a maximum match of 6Ω between channels. Off-leakage current is 0.5nA at +25°C and 5nA at +85°C. The NO_ and NC_ terminals are protected from overvoltage faults up to ±25V during operation and ±40V when powered off.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault protection on NO_ and NC_ terminals prevents damage from overvoltage events while maintaining rail-to-rail signal integrity.
• Pin-compatible with industry-standard DG401/DG403/DG405 devices for easy upgrades.
• TTL- and CMOS-logic compatible inputs ensure seamless integration with standard digital control logic.

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 'EPE' corresponds to the -40°C to +85°C temperature range and 16-pin Plastic DIP package configuration. Confirm that the application requires SPDT switching rather than SPST or DPST variants within the MAX463x family. Ensure input signals do not exceed the ±25V fault protection limit during normal operation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when upgrading legacy designs requiring higher voltage tolerance and fault protection without changing pinouts. Consider the ±25V fault limit for MAX4632 compared to ±36V for MAX4631/MAX4633 if higher fault tolerance is needed. Verify that the 85Ω on-resistance meets the signal path requirements for the specific load conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4632EPE belongs to the MAX4631/MAX4632/MAX4633 family of fault-protected, high-voltage dual analog switches manufactured by Analog Devices/Maxim Integrated. These devices upgrade traditional CMOS switches by adding internal circuitry to handle overvoltage conditions while preserving low on-resistance and rail-to-rail signal capability.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the MAX4631CPE and MAX4633CPE, though these offer different switching configurations (SPST and DPST respectively) and slightly different fault protection voltage limits (+/-36V). Ensure the functional difference between SPDT and other topologies does not impact the circuit design before substitution.
