MAX368EWN

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX368EWN is a fault-protected analog multiplexer manufactured by Analog Devices Inc. (Maxim Integrated). It features a single 8:1 channel configuration housed in an 18-SOIC surface-mount package. The device operates on dual supply voltages ranging from ±4.5 V to ±18 V, with a typical operating voltage of 15 V. Key electrical parameters include a maximum on-resistance of 1.8 kOhms, a maximum propagation delay of 1000 ns, and a maximum power supply current of 2 mA. It supports a switching speed with a maximum turn-on time of 1.5 µs and a turn-off time of 1 µs. The component functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EWN' against the official Maxim Integrated part numbering system to confirm the package type and temperature grade. Confirm RoHS compliance status as historical data indicates potential non-compliance for older batches. Check for active obsolescence notices or product change notifications regarding discontinuation before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single 8:1 analog switch with fault protection is required in a surface-mount application. Ensure the design accommodates the 1.8 kOhm on-resistance and dual supply voltage requirements. Compare against the MAX369 if a quad 4:1 configuration or different pinout is preferred for the same functional family.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX368 belongs to the MAX368/MAX369 family of fault-protected analog multiplexers. It shares core functionality with the MAX369 but differs in channel configuration and package options. The EPN variant offers a through-hole DIP package, while the EWN provides a surface-mount SOIC solution. Both are designed for applications requiring high reliability and protection against overvoltage conditions.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX369EWN serves as a functional alternative within the same family, offering two 4:1 multiplexers in the same 18-SOIC package. Verify pin compatibility and channel mapping differences before substitution.
