DG407DN Equivalent & Substitute Parts
Part Overview
The DG407DN is a dual 8:1 analog multiplexer/demultiplexer IC manufactured by Analog Devices Inc./Maxim Integrated, housed in a 28-PLCC surface mount package. This interface component features 100Ohm on-state resistance and operates across a wide supply voltage range of 5V to 30V (single supply) or ±4.5V to ±20V (dual supply). The DG407DN is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation
Substitution of the DG407DN is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for multiplexer configuration (8:1), circuit count (2), on-state resistance (100Ohm), supply voltage ranges, switching characteristics, and package form factor (28-PLCC). The primary differentiator between the main part and its substitute is product status and compliance certification, not functional or electrical performance.

Engineering Selection Recommendations
The DG407DN+ serves as the direct substitute for the obsolete DG407DN. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications across all functional parameters. The DG407DN+ is the preferred selection for new designs and ongoing production due to its active product status and ROHS3 compliance certification. The DG407DN+ is supplied in tube packaging, whereas the original part's packaging specification is not documented. Both parts maintain equivalent performance in dual 8:1 multiplexer applications requiring 100Ohm on-state resistance and operation across 5V to 30V single supply or ±4.5V to ±20V dual supply voltage ranges.
Frequently Asked Questions (FAQ)
Q: Can the DG407DN+ directly replace the DG407DN in existing designs? A: Yes. The DG407DN+ is electrically and mechanically identical to the DG407DN across all functional parameters, including multiplexer configuration, on-state resistance, supply voltage ranges, switching characteristics, and 28-PLCC package form factor. Direct substitution is supported without circuit modification.
Q: What is the primary difference between DG407DN and DG407DN+? A: The DG407DN is classified as obsolete, while the DG407DN+ maintains active product status. Additionally, the DG407DN+ is ROHS3 compliant, whereas the DG407DN is RoHS non-compliant. Electrical performance is identical between both parts.
Q: Are there any package or supply chain differences? A: The DG407DN+ is supplied in tube packaging. The original DG407DN packaging specification is not documented. Both parts use the same 28-PLCC (11.51x11.51) surface mount package form factor.
Q: Is the DG407DN+ suitable for new product designs? A: Yes. The DG407DN+ is the recommended selection for new designs due to its active product status and ROHS3 compliance certification. It provides identical functionality to the obsolete DG407DN while meeting current regulatory requirements.
Q: What applications require the 8:1 dual multiplexer configuration of these parts? A: The DG407DN and DG407DN+ are used in analog signal routing, data acquisition systems, audio switching, instrumentation, and communication interface applications where multiple analog channels must be selectively routed through a single signal path with minimal on-state resistance and low crosstalk.
