DG405BDY-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG405BDY-T1 is a low-power, high-speed CMOS analog switch manufactured by Vishay Siliconix. It features four independent SPST switches housed in a 16-pin narrow SOIC package with tape and reel packaging. The device operates on dual supplies ranging from ±7 V to ±22 V or single supplies up to 36 V. Key electrical parameters include a maximum on-resistance of 45 Ω, a typical turn-on time of 100 ns, and a maximum off-leakage current of 5 nA at elevated temperatures. It supports an analog signal range of ±15 V and functions within a temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T1' indicates tape and reel packaging for automated assembly. Confirm lead-free status if required, as standard versions may differ from '-E3' variants. Check absolute maximum ratings against system voltage limits to prevent permanent damage. Ensure operating conditions remain within the specified -40 °C to +85 °C range for guaranteed performance.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring fast switching speeds and low power consumption in portable devices. Compare on-resistance flatness across the full analog voltage range against circuit requirements. Evaluate supply voltage compatibility, noting support for both single and dual supply configurations. Consider thermal derating requirements if power dissipation exceeds 600 mW.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG401B, DG403B, and DG405B series, which serve as improved replacements for the legacy DG401/403/405 models. The DG405B specifically provides four SPST switches arranged in two pairs. It utilizes Vishay's proprietary high-voltage silicon-gate process to achieve high voltage ratings and reliable break-before-make action where applicable.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG405BDY-E3 is the lead-free equivalent version of this component. Verify pinout compatibility when substituting with other members of the DG40xB family, such as the DG403BDY-T1, noting differences in internal switch configuration.
