MAX4633CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4633CSE is a high-voltage, dual analog switch featuring fault-protected inputs and Rail-to-Rail signal handling capabilities. It contains two normally open double-pole/single-throw (DPST) switches housed in a 16-pin Narrow SOIC 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 an on-resistance of 85Ω maximum at +25°C, off-leakage current of 0.5nA at +25°C, and turn-on/turn-off times of 150ns and 100ns respectively. The NO_ and NC_ terminals are protected from overvoltage faults up to 36V during power-up or power-down.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault protection for NO_ and NC_ terminals against overvoltages up to 36V during operation and 40V when powered off.
• Rail-to-Rail signal handling capability allowing signals to pass through the switch even if they slightly exceed the supply rails.
• TTL- and CMOS-logic compatible digital inputs ensuring compatibility with standard logic families across various supply voltages.
• Pin-compatible design with industry-standard DG401/DG403/DG405 devices for easy integration into existing layouts.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CSE' corresponds to the 0°C to +70°C temperature range and the 16-pin Narrow SOIC package configuration. Confirm that the component meets RoHS compliance standards as indicated by the '+' suffix in the manufacturer's part number. Ensure that the application environment does not exceed the absolute maximum ratings for voltage and current to maintain device reliability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4633CSE when dual DPST switching functionality with high-voltage fault protection is required. This component is suitable for applications needing rail-to-rail signal integrity without power-supply sequencing constraints. Consider the 85Ω on-resistance and 0.5nA leakage current specifications to ensure they meet the system's signal fidelity requirements under the intended operating temperature conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4633CSE belongs to the MAX4631/MAX4632/MAX4633 family of fault-protected, high-voltage dual analog switches manufactured by Analog Devices Inc./Maxim Integrated. These devices upgrade traditional CMOS switches by incorporating parallel N-channel and P-channel MOSFETs for improved on-resistance and fault handling. The MAX4633 specifically provides two DPST switches, distinguishing it from the SPST (MAX4631) and SPDT (MAX4632) variants within the same pin-compatible series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4633CSE is pin-compatible with the industry-standard DG401, DG403, and DG405 switches. However, direct replacement requires verification that the legacy components do not require the specific fault-protection features provided by the MAX4633. Ensure that the replacement maintains the required voltage ratings and signal handling characteristics for the target application.
