MAX354EWE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX354EWE is a single-channel, 8-to-1 fault-protected analog multiplexer housed in a 16-pin Wide SOIC package. It operates from a single supply of 4.5V to 36V or dual supplies of ±4.5V to ±18V. The device features a maximum on-resistance of 350Ω and input leakage current below 0.5nA at +25°C. Digital inputs are compatible with TTL and CMOS logic without pull-up resistors. The component provides break-before-make switching and protects against overvoltage up to 40V beyond the supply rails.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Series N-channel, P-channel, N-channel structure for continuous fault protection
• Guaranteed break-before-make operation prevents channel shorting
• TTL and CMOS logic compatibility without 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
• Avionics signal routing
• Automated test equipment (ATE)
• Redundant and backup systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' confirms the -40°C to +85°C industrial temperature range. Confirm the 'W' indicates the 16-Wide SOIC package. Ensure the datasheet revision matches the required specifications. Check RoHS compliance status if environmental regulations apply. Validate pinout alignment with the target PCB footprint before integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part for applications requiring high-voltage fault tolerance up to 40V. Use for multiplexing signals where low leakage and TTL/CMOS compatibility are critical. Consider the 350Ω on-resistance for signal integrity requirements. Verify that the 16-pin Wide SOIC package fits the assembly constraints. Evaluate the need for demultiplexing capabilities as the device supports both functions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX354 is part of the MAX354/MAX355 family of fault-protected analog multiplexers. It serves as a pin-compatible alternative to older Maxim devices like the MAX358 and DG458. The MAX355 variant offers dual 4-channel configurations within the same package footprint. This series is designed for robust signal routing in harsh electrical environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX354EWE is pin-compatible with the ADG508F. It also serves as an improved second source for the MAX358 and DG459. Verify voltage ratings and on-resistance characteristics when substituting these components.
