MAX388EWG+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX388EWG+ is a high-voltage, fault-protected analog multiplexer manufactured by Analog Devices under the Maxim Integrated brand. It features an 8-channel to 1-line configuration housed in a 24-SOIC package. The device supports dual supply voltages ranging from ±4.5V to ±18V. Key electrical specifications include a maximum on-resistance of 3 kOhms and channel-to-channel matching of 300 Ohms. Switching performance is defined by a maximum turn-on time of 1.5 µs and a turn-off time of 1 µs. Additional parameters include 55 pC charge injection, 500 pA maximum leakage current, and operation 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 potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements prior to procurement. Ensure storage conditions adhere to moisture sensitivity level guidelines to maintain device integrity during assembly processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high-voltage handling and fault protection are required for analog signal paths. The 3 kOhm on-resistance suits applications where lower bandwidth or higher impedance sources are present. Compare against lower-resistance alternatives if signal fidelity at higher frequencies is critical. Verify that the 24-SOIC footprint aligns with existing PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX388 family of analog multiplexers designed for demanding industrial environments. It complements other devices in the series offering different channel counts or resistance profiles. The EWG+ suffix indicates a specific tape-and-reel or tube packaging variant compliant with environmental standards, distinguishing it from non-compliant or legacy versions.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes may include other MAX388 variants with compatible pinouts but differing packaging or temperature ranges. Cross-reference with MAX388EWG for identical functionality without RoHS certification if necessary. Evaluate alternative high-voltage multiplexers from the same manufacturer ensuring similar on-resistance and voltage ratings.
