DG303BDY-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG303BDY-T1 is a dual single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates within a supply voltage range of 13 V to 36 V for single supplies or ±15 V for dual supplies. The device features a maximum on-resistance of 50 Ohms and supports a DC switch current of 100 mA. Electrical performance includes a maximum turn-on time of 150 ns and a maximum turn-off time of 130 ns. Power dissipation is rated at 600 mW, with a maximum supply current of 1 mA. The component functions reliably across an operating temperature range from -40°C to +85°C and is housed in a surface-mount SOIC-14 package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix T1 against official datasheets to confirm tape-and-reel packaging requirements. Confirm RoHS compliance status as historical records indicate potential non-compliance for certain variants. Validate that the SOIC-14 footprint matches the target PCB layout before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent signal paths are required within a compact surface-mount form factor. Ensure the application voltage does not exceed the 36 V single-supply limit. Consider the 50 Ohm on-resistance impact on signal integrity for high-precision applications compared to lower-resistance alternatives.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG303 series of analog switches, designed for general-purpose signal routing. It serves as a surface-mount alternative to through-hole DIP packages like the DG303BDJ. The device integrates two independent SPDT switches into a single integrated circuit for efficient board space utilization.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct pin-to-pin replacements such as the DG303ACJ+ only if explicitly validated by the manufacturer.
