DG403DJ-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG403DJ-E3 is a CMOS analog switch manufactured by Vishay Semiconductors, housed in a 16-pin PDIP package. It integrates four single-pole single-throw (SPST) channels. The device supports single or dual power supplies ranging from 13 V to 36 V for single supply operation, and ±15 V for dual supply configurations. Key electrical parameters include a maximum on-resistance of 45 Ohms, a maximum turn-on time of 150 ns, and a maximum turn-off time of 100 ns. The component operates within a temperature range of -40°C to +85°C and features a maximum power dissipation of 450 mW.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific manufacturer source, as this component is listed under both Vishay Semiconductors and Analog Devices/Maxim Integrated in public records. Confirm the RoHS compliance status and ensure the PDIP-16 through-hole package matches the design requirements. Check current availability status as some distributors list this part as discontinued or limited stock.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four isolated analog signals require switching with moderate speed and low on-resistance. Ensure the circuit design accommodates the 13 V to 36 V single supply or ±15 V dual supply range. Consider the 45 Ohm on-resistance variation and the 450 mW power dissipation limit for thermal management in the final application.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG40x series of CMOS analog switches, which are widely used for general-purpose signal switching. The DG403 variant specifically offers four SPST channels, distinguishing it from multiplexer variants like the DG408 or other configurations in the same family. It serves as a standard solution for connecting multiple analog sources to a common destination.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public records indicate the DG403DJ+ from Analog Devices Inc./Maxim Integrated as a direct substitute. Verify pin compatibility and electrical parameter equivalence before replacement.
