DG300BDJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG300BDJ is a dual single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 10 V to 36 V or dual supplies of ±5 V to ±18 V. The device features a maximum on-resistance of 25 Ohms and a maximum on-resistance matching of 10 Ohms. Switching times are specified with a maximum turn-on time of 150 ns and a maximum turn-off time of 130 ns. It supports a continuous DC switch current of 100 mA and has a maximum power dissipation of 470 mW. The component is housed in a 14-pin PDIP package and functions within an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix and environmental compliance status before ordering, as legacy components may have varying RoHS declarations. Confirm availability through authorized distributors, noting that older siliconix parts often have limited stock. Ensure the procurement channel provides genuine Vishay Siliconix products to avoid counterfeit risks associated with discontinued series.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPDT switching is required at higher voltages than standard CMOS switches allow. Compare on-resistance and leakage specifications against system requirements. Consider the PDIP package size constraints versus surface-mount alternatives if space is limited. Verify that the supply voltage range aligns with the application's power rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG300BDJ belongs to the DG300 series of CMOS analog switches from Vishay Siliconix. This series is known for high-speed operation and low power consumption. The BDJ suffix indicates a dual SPDT configuration in a 14-pin plastic dual in-line package. It is part of a broader family including single and quad variants designed for general-purpose analog signal switching.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for direct pin-compatible replacements such as the DG300BCJ or DG300BEJ if different package options are needed. Evaluate cross-brand equivalents like those from Maxim Integrated or Texas Instruments that offer similar voltage ratings and SPDT configurations. Ensure any substitute matches the on-resistance and switching speed parameters.
