MAX394MJP

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX394MJP is a quad single-pole double-throw (SPDT) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features four independent channels in a 20-pin ceramic dual flatpack (CDIP) package designed for military and high-reliability applications. The device operates on a single supply voltage ranging from 2.4 V to 8 V, with a typical rated voltage of 5 V. Key electrical specifications include a maximum on-time of 130 ns and an off-time of 75 ns. The component utilizes CMOS technology and supports surface-mount or through-hole installation depending on the specific variant configuration, ensuring robust signal routing in demanding environments.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the exact package type and suffix designation when sourcing, as military variants often require specific handling and authentication. Confirm RoHS compliance status if applicable to your project requirements, noting that some legacy military parts may have different environmental certifications. Ensure the supplier provides traceability documentation consistent with defense industry standards.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when multiple isolated signal paths are required within a compact form factor. Consider the 130 ns switching speed for applications where moderate latency is acceptable. Evaluate the 2.4 V to 8 V operating range against your system's power supply constraints to ensure optimal performance without exceeding the maximum voltage limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX394 belongs to the broader family of analog switches produced by Maxim Integrated, now part of Analog Devices. This specific model represents the military-grade version, distinguished by its ceramic construction and extended temperature stability compared to commercial plastic counterparts. It serves as a critical interconnect solution in systems prioritizing signal integrity and physical ruggedness over cost minimization.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements should be sought from the same manufacturer line to maintain pin compatibility and electrical characteristics. Verify that any substitute part matches the CDIP-20 package dimensions and meets the same military qualification standards. Cross-reference datasheets to confirm identical on-resistance and leakage current specifications.
