MAX4632CSE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4632CSE+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 85Ω at +25°C, an off-leakage current of 0.5nA at +25°C, and a maximum 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 Procurement Notes

Verify the specific suffix 'CSE' corresponds to the commercial temperature range and narrow SOIC package configuration required for your design. Confirm that the '+T' designation aligns with your preferred reel packaging specifications. Ensure compatibility with existing board layouts due to pin-out similarities with legacy parts.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection is critical for protecting downstream circuitry from input overvoltages. The MAX4632 offers SPDT functionality suitable for signal routing applications. Verify that the ±25V fault protection limit meets your system's voltage requirements, as other variants offer different protection levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4631/MAX4632/MAX4633 family of fault-protected analog switches. While sharing similar architecture and pinouts, the MAX4632 specifically provides two SPDT switches, distinguishing it from the SPST MAX4631 and DPST MAX4633. All variants share the same core fault-protection technology and Rail-to-Rail operation.
