DG405DJ-E3

Overview

The DG405DJ-E3 is a CMOS analog switch IC manufactured by Vishay Siliconix, housed in a 16-pin PDIP package. It features four independent SPST channels with a maximum on-resistance of 45 Ohms. The device supports single or dual power supplies, operating within a voltage range of 13 V to 36 V for single supply and ±15 V for dual supply configurations. Key electrical parameters include a maximum propagation delay of 150 ns, an off-time of 100 ns, and a maximum supply current of 1 uA. It functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• CMOS technology ensures low power consumption and compatibility with standard logic families.
• Four independent single-pole single-throw (SPST) channels provide flexible signal routing capabilities.
• Low on-resistance characteristic supports accurate analog signal transmission.
• Robust construction allows operation under wide supply voltage conditions.

Applications

• Data acquisition systems requiring precise analog signal switching.
• Industrial process control loops involving sensor signal multiplexing.
• Test and measurement equipment needing reliable analog path selection.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinuation status. Confirm RoHS compliance documentation matches the specific batch requirements. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent package damage during soldering processes.

Selection Notes

Select this component when four isolated analog switches are required in a through-hole configuration. Compare on-resistance specifications against load requirements to ensure signal integrity. Verify that the supply voltage range aligns with the system's available power rails. Consider thermal dissipation limits if multiple channels operate simultaneously under high load conditions.

Part Context

This part belongs to the DG405 series of analog switches, designed for general-purpose signal switching applications. It complements other devices in the family such as the DG406 and DG409, offering distinct channel counts and pinout configurations. The E3 suffix indicates lead-free composition compliant with environmental directives.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate alternative components based on matching pinout, on-resistance, and supply voltage specifications. Verify functional equivalence before implementing any cross-references in design schematics.
