MAX358EWE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX358EWE+ is a fault-protected analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features an 8-channel, single-ended configuration housed in a 16-pin SOIC-Wide package. The device operates on dual supplies ranging from ±4.5V to ±18V, with a typical nominal voltage of ±15V. Key electrical parameters include a maximum on-resistance of 1.8 kΩ and switching times (Ton/Toff) of 300ns. It supports a wide operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrated fault protection circuitry safeguards the device against input voltage excursions beyond the supply rails.
• CMOS technology enables low power consumption while maintaining high-speed signal switching capabilities.

Analog Switches, Multiplexers, Demultiplexers Applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended industrial temperature range (-40°C to +85°C). Confirm the '+' suffix denotes RoHS compliance. Ensure the package matches the 16-SOIC-Wide specification for PCB footprint compatibility. Cross-reference the manufacturer's latest datasheet for any pinout revisions or handling precautions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection is required for inputs exceeding supply voltages. Compare on-resistance and leakage current specifications against similar multiplexers like the MAX359 if channel count differs. Verify that the 1.8 kΩ on-resistance meets the application's signal integrity requirements. Consider the 300ns switching speed for timing constraints in the system design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX358 family of fault-protected analog multiplexers. It shares functional similarities with the MAX359 but offers different channel configurations. The MAX358 series is designed for robust performance in harsh environments where input overvoltage events are possible.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other variants within the MAX358 family such as MAX358CWE+ or MAX358DWE+, differing primarily in temperature grades. Verify package compatibility and electrical parameter alignment before substitution.
