DG301BDJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG301BDJ is a single-channel SPDT analog switch manufactured by Vishay Siliconix. It operates within a dual supply voltage range of ±15 V and supports single supply configurations up to 30 V. The device features a maximum on-resistance of 50 Ohms, with a typical turn-on time of 300 ns and turn-off time of 250 ns. It is housed in a 14-pin PDIP package designed for through-hole mounting. The component supports a continuous DC switch current of 100 mA and maintains operation across an extended temperature range from -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Single-pole double-throw (SPDT) switching configuration for signal routing
• High thermal stability supporting industrial and military temperature ranges
• Low power consumption suitable for battery-operated systems

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring signal multiplexing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix BDJ confirms the 14-pin plastic DIP package and commercial/industrial grade rating. Confirm RoHS compliance status as older manufacturing runs may differ. Check for obsolescence notices or lifecycle changes directly from Vishay documentation before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single high-current analog path requires switching between two sources. Ensure the system voltage does not exceed the absolute maximum ratings for both positive and negative rails. Consider the 50 Ohm on-resistance impact on signal integrity for low-voltage applications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG series of CMOS analog switches known for robust performance in harsh environments. It serves as a fundamental building block for creating configurable analog front-ends in measurement devices and automated testing machinery.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible alternatives include the DG301AAK for ceramic DIP packages or other Vishay DG301 variants with different suffixes indicating package type. Verify electrical parameters match exactly when substituting.
