MAX355CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX355CPE+ is a dual 4-channel fault-protected analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. 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 less than 0.5nA at +25°C. It provides overvoltage protection up to 40V beyond the supply rails during power-up, power-down, and fault conditions. The component is housed in a 16-pin Plastic DIP package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault-protected series N-channel, P-channel, N-channel structure safeguards against overvoltage up to 40V beyond supply rails.
• Guaranteed break-before-make operation prevents simultaneous connection of multiple inputs.
• All switches turn off automatically when power supplies are removed.
• Compatible with standard TTL and CMOS logic levels without requiring pull-up resistors.

Analog Switches, Multiplexers, Demultiplexers Applications

• Data-Acquisition Systems
• Industrial and Process Control
• Avionics
• ATE Equipment
• Signal Routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CPE+' corresponds to the 16-pin Plastic DIP package and the commercial temperature range (0°C to +70°C). Confirm that the ordering information matches the manufacturer's current datasheet revision, as suffixes may indicate variations in testing or packaging. Ensure compatibility with the required voltage and logic interface specifications for the target application.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring high-voltage fault protection and bidirectional signal routing. The dual 4-channel configuration allows independent control of two switch groups. Verify that the 350Ω on-resistance meets the system's signal integrity requirements. Consider the ±4.5V to ±18V dual supply capability if negative voltages are present in the signal path.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX355CPE+ belongs to the MAX354/MAX355 family of fault-protected analog multiplexers. It serves as a pin-compatible alternative to older Maxim parts like the MAX358/MAX359 and ADI parts such as the ADG508F/ADG509F. This family is designed for robust signal switching in harsh environments where overvoltage events are possible.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible replacements include the ADG508F and ADG509F. Direct functional equivalents within the same family are the MAX354CPE+ (single 8-channel version) and other variants in the MAX35x series with matching package and temperature ratings.
