MAX354EWE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX354EWE+T is a fault-protected analog multiplexer housed in a 16-pin Wide SOIC package. It features a single 8-channel configuration with a maximum on-resistance of 350 Ω and an input leakage current of less than 0.5 nA at +25°C. The device operates from a single supply ranging from 4.5V to 36V or dual supplies from ±4.5V to ±18V. It provides continuous overvoltage protection up to ±40V beyond the supply rails during power-up, power-down, and fault conditions. The component ensures TTL and CMOS logic compatibility without requiring pull-up resistors.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Series N-channel, P-channel, N-channel structure protects against overvoltages up to 40V beyond supply rails
• Guaranteed break-before-make operation prevents simultaneous connection of multiple channels
• All switches turn off automatically when power supplies are removed
• Compatible with standard TTL and CMOS logic levels without external pull-up resistors

Analog Switches, Multiplexers, Demultiplexers Applications

• Data-acquisition systems
• Industrial and process control equipment
• Avionics signal routing
• Automated test equipment (ATE)
• Redundant and backup systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix 'E' corresponds to the -40°C to +85°C industrial temperature range and 'W' indicates the 16-Wide SOIC package. Confirm the '+' suffix denotes lead-free and RoHS compliance status as per manufacturer specifications. Ensure the component source matches Analog Devices Inc. or Maxim Integrated documentation for authenticity.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part for applications requiring high-voltage fault protection on analog signals. Verify that the required channel count fits the single 8-channel architecture. Check if the 350 Ω on-resistance meets system impedance requirements. Confirm that the operating voltage range aligns with the available single or dual power supplies in the design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX354/MAX355 family of fault-protected analog multiplexers manufactured by Maxim Integrated, now part of Analog Devices Inc. The MAX354 variant specifically provides eight independent channels, whereas the MAX355 offers two four-channel configurations. Both share identical pinouts and core protection circuitry.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet identifies the ADG508F/ADG509F as pin-compatible alternatives. It also notes improved second-source compatibility with the MAX358/MAX359 series. Verify electrical parameters such as on-resistance and leakage currents before substituting these parts.
