DG271BDY-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG271BDY-E3 is a quad single-pole single-throw (SPST) analog switch IC manufactured by Vishay Siliconix. It features four independent channels in a 16-pin SOIC-Narrow package. The device operates with a dual supply voltage of ±15 V and supports a maximum on-resistance of 50 Ohms. Switching performance includes a maximum turn-on time of 65 ns and a maximum turn-off time of 65 ns. It functions within an ambient temperature range of -40°C to +85°C, with a maximum power dissipation of 600 mW and a maximum supply current of 7.5 mA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific tape-and-reel versus tube packaging options prior to ordering. Ensure the supplier provides valid traceability documentation to mitigate risks associated with counterfeit components in the supply chain.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required with ±15 V dual supply operation. Compare on-resistance specifications against system requirements if lower resistance values are necessary. Consider alternative packages such as DIP or wider SOIC variants if thermal management or board layout constraints differ from the narrow SOIC footprint.
