DG302BDJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG302BDJ is a dual single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates with 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 50 Ohms and supports a continuous DC switch current of 100 mA. Switching times are specified at a maximum of 150 ns for turn-on and 130 ns for turn-off. It 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 Feature Summary

• Dual SPDT configuration providing two independent signal paths

• Robust current handling capability with 100 mA continuous DC switch rating

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in data acquisition systems
• Multiplexing sensor inputs
• Test and measurement equipment signal switching

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors as the DG302BDJ may be discontinued or subject to obsolescence notices. Confirm RoHS compliance status and lead times directly with the manufacturer or certified suppliers before integration into production schedules.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high voltage single-supply operation and moderate speed switching are required. Ensure the application does not exceed the 100 mA continuous current limit. Consider thermal dissipation constraints given the 470 mW power dissipation rating in the PDIP package.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG series of CMOS analog switches from Vishay Siliconix. It shares functional similarities with other devices in the family but is distinguished by its specific dual SPDT topology and high-voltage single-supply capability compared to lower-voltage alternatives.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for direct pin-compatible replacements such as the DG302ACJ or equivalent parts from other manufacturers if the DG302BDJ is unavailable. Verify that substitute components meet the same voltage, current, and switching speed specifications.
