DG441BDJ

Analog Switches, Multiplexers, Demultiplexers Overview

The Vishay Siliconix DG441BDJ is a monolithic quad single-pole single-throw (SPST) CMOS analog switch housed in a 16-pin Plastic DIP package. It provides high-speed switching with a typical turn-on time of 120 ns and low on-resistance of 45 Ω at room temperature, extending to a maximum of 95 Ω across the full operating range. The device supports dual supplies from ±7 V to ±22 V or a single supply up to 36 V, with an analog signal range matching the supply rails. Power consumption is minimized at 1 mW, and charge injection is limited to -1 pC, making it suitable for precision applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against current Vishay documentation to confirm package type and compliance status. The base part number corresponds to the 16-pin Plastic DIP variant. Confirm RoHS compliance requirements by checking for the -E3 suffix if lead-free material is mandatory for the assembly process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG441BDJ when a through-hole 16-pin DIP package is required for prototyping or legacy board designs. Ensure the application voltage does not exceed the absolute maximum ratings of 44 V between supplies. Verify that the 80 Ω to 95 Ω maximum on-resistance meets the signal integrity requirements compared to lower-resistance alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG441BDJ belongs to the DG441B/DG442B series, which are upgraded versions of the original DG441/DG442 devices. This family utilizes Vishay's high-voltage silicon-gate process to deliver improved performance characteristics such as reduced charge injection and faster switching speeds while maintaining compatibility with standard digital logic levels.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG441BDJ-E3 is the RoHS-compliant version of this component. For surface-mount requirements, the DG441BDY-E3 (SOIC-16) offers equivalent electrical specifications in a different package form factor.
