DG405BDY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG405BDY is a low-power, high-speed CMOS analog switch manufactured by Vishay Siliconix. It features four independent SPST switches in two pairs within a 16-pin narrow SOIC package. The device supports a maximum supply voltage of 44 V and an analog signal range of ±15 V. Key electrical parameters include a typical on-resistance (RDS(on)) of 23 Ω with a maximum of 45 Ω, and a turn-on time (tON) of 100 ns. It operates from -40 °C to +85 °C and offers low leakage current.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the exact ordering suffix against the manufacturer's documentation to confirm package type and lead-free status. The standard commercial part number is DG405BDY, while the lead-free variant carries the -E3 suffix. Confirm availability through authorized distributors as production status may vary.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four independent single-pole single-throw channels are required in a compact surface-mount package. Ensure the application voltage does not exceed the 44 V absolute maximum rating. Verify that the 23 Ω typical on-resistance meets the signal integrity requirements of the specific circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG405BDY belongs to the DG401B, DG403B, and DG405B series, which serve as improved replacements for the legacy DG401/403/405 models. This series combines high speed with low power consumption, making it suitable for portable and battery-powered applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The lead-free version DG405BDY-E3 is the direct environmental equivalent. For different channel configurations within the same family, consider the DG401BDY (two SPST switches) or the DG403BDY (four SPST switches in NO/NC combinations).
