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 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 power dissipation of 696mW. The component supports TTL and CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault protection for NO and NC terminals against overvoltage faults up to ±25V during operation and ±40V when powered off.
• Rail-to-Rail signal handling ensures unambiguous outputs during fault transitions without requiring power-supply sequencing.
• Pin-compatible design allows direct replacement for industry-standard DG401/DG403/DG405 devices.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the temperature range and packaging format. The 'E' suffix indicates an extended temperature range of -40°C to +85°C, while the 'C' suffix denotes commercial range. Confirm the package type matches the target PCB footprint, as this part number specifies the Narrow SOIC-16 configuration. Cross-reference the manufacturer's latest documentation for any lifecycle status changes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4632ESE+ when dual SPDT switching with high-voltage fault protection is required. Ensure the application voltage does not exceed the ±25V limit for the MAX4632 variant during power-on conditions. Verify that the load current requirements remain within the continuous current ratings to prevent device damage. Consider the on-resistance match specifications if channel balancing is critical for the signal path integrity.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX463x family of fault-protected analog switches, which also includes the MAX4631 (dual SPST) and MAX4633 (dual DPST). All members share identical pinouts and core protection circuitry but differ in their internal switch configurations. The MAX4632 specifically provides the flexibility of both normally open and normally closed contacts for each channel.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4632ESE+ is pin-compatible with the DG403. When substituting legacy parts, verify that the original design accommodates the higher fault-protection voltage limits and rail-to-rail output clamping behavior unique to the MAX463x series.
