MAX369EWN

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX369EWN is a dual SP4T analog switch manufactured by Analog Devices Inc./Maxim Integrated, housed in an 18-SOIC surface-mount package. It operates on dual supplies ranging from ±4.5V to ±18V. The device features a maximum on-resistance of 1.8 kΩ with a channel-to-channel matching of 180 Ω. Switching times are specified at a maximum of 1.5 µs for turn-on and 1 µs for turn-off. Key electrical characteristics include a charge injection of 55 pC, off-state leakage current of 5 nA, and channel capacitance values of 5 pF and 12 pF. It functions within a temperature range of -40°C to 85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinued status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity upon receipt, ensuring no damage to the 18-SOIC leads. Check datasheet revisions for any pinout or electrical parameter updates prior to integration into new designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent 4:1 multiplexing is required with high-voltage dual supply compatibility. Consider the 1.8 kΩ on-resistance limit for signal attenuation constraints. Evaluate the 18-SOIC footprint against available PCB space. Compare switching speed and leakage specifications against alternative switches if lower resistance or faster transition times are necessary for the specific application.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX369 belongs to the MAX368/MAX369 family of analog switches. It shares similar electrical characteristics with the MAX368 but differs in channel configuration, offering two SP4T circuits instead of one 8:1 circuit. Both devices utilize the same 18-pin package and operate under identical supply voltage ranges. This family provides robust analog signal switching solutions for industrial and communication applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other dual SP4T analog switches from Analog Devices or Maxim Integrated, ensuring compatible package dimensions, supply voltage ranges, and electrical parameters before substitution.
