MAX354EPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX354EPE+ is a single 8-channel 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 350 Ω, input leakage current less than 0.5nA at +25°C, and break-before-make operation. Digital inputs feature 0.8V and 2.4V logic thresholds for TTL and CMOS compatibility without pull-up resistors.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Fault protection circuitry safeguards sensitive components against overvoltage conditions up to 40V beyond supply rails.
• Break-before-make switching action prevents simultaneous connection of multiple input channels to the output.
• TTL and CMOS logic compatibility is ensured through specific digital input voltage thresholds.
• All switches turn off automatically when power supplies are removed.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the manufacturer markings and package integrity upon receipt. Confirm that the ordering suffix matches the required temperature range and packaging specifications. Ensure the receiving environment meets electrostatic discharge protection standards to prevent damage to the internal circuitry during handling and installation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring high-voltage fault protection and reliable signal routing in industrial environments. Consider the 350 Ω on-resistance and leakage characteristics when designing for precision analog signals. Verify that the system power supply ranges fall within the specified operational limits to ensure proper functionality and longevity of the multiplexer.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX354EPE+ belongs to the MAX354/MAX355 family of fault-protected analog multiplexers. It serves as an improved second source for older models like the MAX358/MAX359 and DG458/DG459. The device is pin-compatible with ADI's ADG508F/ADG509F, facilitating direct replacements in existing designs that require enhanced fault protection capabilities.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX354EPE+ is pin-compatible with the ADG508F and ADG509F. It also serves as an improved second source for the MAX358/MAX359 and DG458/DG459. When substituting, verify that the replacement part supports the same voltage ranges and fault protection requirements.
