MAX354EWE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX354EWE+ is a single-channel, 8-to-1 fault-protected analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It utilizes a series N-channel, P-channel, N-channel structure to protect against overvoltage up to 40V beyond the supply rails during power-up, power-down, and fault conditions. The device operates from a single 4.5V to 36V supply or ±4.5V to ±18V dual supplies. Key electrical parameters include a maximum on-resistance of 350Ω, input leakage current less than 0.5nA at +25°C, and TTL/CMOS logic compatibility with 0.8V and 2.4V thresholds. It features guaranteed break-before-make operation and consumes less than 1.5mW of power.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Series FET protection scheme limits input current to sub-microamp levels during overvoltage events
• Guaranteed break-before-make switching action prevents simultaneous connection of multiple inputs
• TTL and CMOS logic compatibility without requiring external pull-up resistors
• All switches turn off automatically when power supplies are removed

Analog Switches, Multiplexers, Demultiplexers Applications

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

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking for the Maxim Integrated or Analog Devices branding and the specific 'E' suffix indicating the -40°C to +85°C operating temperature range. Confirm the package type matches the 16-pin Wide SOIC specification. Ensure the datasheet revision aligns with the latest technical documentation provided by the manufacturer to guarantee compliance with all absolute maximum ratings and electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX354EWE+ when a single 8-channel multiplexer with high-voltage fault protection is required. This part is suitable for designs needing operation across wide supply ranges, including single-supply configurations up to 36V. Consider this device if the application demands low leakage currents and compatibility with standard digital logic levels. Verify that the 350Ω on-resistance meets the signal integrity requirements of the specific circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX354EWE+ belongs to the MAX354/MAX355 family of fault-protected analog multiplexers. It serves as a pin-compatible replacement for older generations such as the DG458/DG459 and acts as an improved second source for the MAX358/MAX359. The 'E' designation specifically denotes the extended industrial temperature range of -40°C to +85°C, distinguishing it from commercial grade variants.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX354EWE+ is pin-compatible with the ADG508F. Designers may also consider it as an improved alternative to the MAX358 and DG458 devices. When substituting, verify that the new component supports the required voltage ranges and fault-protection specifications.
