DG303BDY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG303BDY is a dual-channel analog switch IC manufactured by Vishay Siliconix, housed in a 14-pin SOIC surface-mount package. It features two single-pole double-throw (SPDT) channels with a maximum on-resistance of 50 Ohms. The device operates on dual power supplies ranging from ±13 V to ±15 V and supports a continuous DC switch current of 100 mA. Switching performance includes a maximum turn-on time of 150 ns and a maximum turn-off time of 130 ns. It functions within an industrial temperature range of -40°C to +85°C, dissipating up to 600 mW of power.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official datasheets. Check for obsolescence notices or lifecycle changes before procurement planning. Ensure storage conditions meet semiconductor handling standards to prevent moisture damage.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent signal paths are required in a small footprint. The 100 mA current rating suits moderate load applications compared to lower-current alternatives. Verify that the ±15 V supply requirement aligns with system power architecture. Consider thermal dissipation limits in high-density PCB layouts.

Analog Switches, Multiplexers, Demultiplexers Part Context

Part of the DG series analog switches, designed for general-purpose signal switching. The BDY suffix denotes the specific SOIC-14 package variant. This model bridges legacy DIP versions with modern surface-mount requirements while maintaining similar electrical characteristics to other DG30x family members.
