MAX358EWE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX358EWE+ is a fault-protected analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features eight single-ended channels configured as an 8:1 multiplexer within a 16-pin SOIC-Wide package. The device operates on dual supplies ranging from ±4.5V to ±18V, with a typical operating voltage of 15V. Key electrical parameters include a maximum on-resistance of 1.8 kΩ and switch times (Ton/Toff) of up to 300ns. It supports a wide operating temperature range from -40°C to +85°C and draws a maximum supply current of 1mA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' confirms the extended industrial temperature range (-40°C to +85°C) and 'WE+' indicates the SOIC-Wide package with lead-free RoHS compliance. Confirm the manufacturer designation matches Analog Devices Inc. or Maxim Integrated to ensure authenticity. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when fault protection is required for analog signals exceeding standard supply rails. Ensure the application utilizes dual power supplies compatible with the ±4.5V to ±18V range. Verify that the 1.8 kΩ on-resistance meets the signal integrity requirements of the connected circuitry compared to lower-resistance alternatives in the MAX35x family.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX358 series of fault-protected analog multiplexers. It shares functional similarities with the MAX359 but differs in channel count and configuration. The MAX358 provides eight channels, whereas other variants may offer different configurations. It is designed for robust performance in noisy industrial environments where input protection is critical.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other parts within the MAX358 family such as MAX358CWE+ or MAX358DWE+, depending on temperature grade and packaging preferences. Cross-reference with MAX359 variants if channel count differences are acceptable.
