DG307BDJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG307BDJ is a monolithic CMOS analog switch from the Vishay Siliconix DG series, housed in a 14-pin Plastic DIP package. It contains two independent Single-Pole Double-Throw (SPDT) channels designed for communications, instrumentation, and process control applications. The device supports ±15 V input ranges and single supply operation. Key electrical parameters include a maximum on-resistance of 50 Ω at room temperature, a turn-on time of 110 ns, and a turn-off time of 70 ns. It operates within a temperature range of -40 °C to +85 °C with a power dissipation rating of 470 mW.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm the specific ordering suffix matches the required lead-free status if applicable. Review the datasheet for absolute maximum ratings to ensure operational limits are not exceeded. Validate RoHS compliance documentation against current regulatory requirements before integration into production designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPDT switching functionality is required in a compact DIP footprint. Ensure the application voltage does not exceed the ±20 V limit for optimal performance. Consider the 50 Ω on-resistance variation across the full analog signal range when designing precision signal paths. Verify that the 110 ns switching speed meets the timing requirements of the target system.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG304B/DG306B/DG307B family of CMOS analog switches. The DG307B variant specifically integrates two SPDT switches, whereas the DG304B contains four SPST switches and the DG306B offers a different configuration. All variants share the same PLUS-40 CMOS process technology for low power consumption and fast switching characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG307BDJ-E3 is the lead-free version of this component. Other members of the DG304B/306B/307B family may serve as functional alternatives depending on the required switch configuration (SPST vs SPDT). Verify pin compatibility and on-resistance specifications when substituting with other CMOS analog switches.
