Overview
The DG387BDJ-E3 is a single-channel SPDT analog switch manufactured by Vishay Siliconix. It operates within a supply voltage range of 0 V to 15 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 30 mA. Switching performance includes a maximum turn-on time of 150 ns and a maximum turn-off time of 130 ns. Power dissipation is rated at 470 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 PDIP-14 package.
Feature Summary
- Single-pole double-throw (SPDT) configuration for signal routing applications
- Low power consumption with minimal supply current draw
- Robust mechanical construction suitable for through-hole mounting
Applications
- Signal multiplexing in data acquisition systems
- Audio and video signal path switching
- Instrumentation input selection circuits
Procurement Notes
Verify the specific suffix E3 confirms RoHS compliance status against current manufacturer documentation. Confirm availability as the base model DG387BDJ is listed as obsolete in distributor records. Ensure the PDIP-14 through-hole package aligns with existing PCB footprints before procurement planning.
Selection Notes
Select this component when a single SPDT switch is required with moderate speed and low on-resistance. Compare against the DG381 series if dual independent SPST channels are needed instead. Verify that the 15 V maximum supply voltage meets system requirements. Check thermal constraints given the 470 mW power dissipation rating in the DIP-14 package.
Part Context
This part belongs to the DG series of CMOS analog switches produced by Vishay Siliconix. The series offers various configurations including SPST, SPDT, and multiplexer options. The DG387 variant specifically provides a single channel with two states, distinguishing it from multi-channel counterparts like the DG201 or DG536.
Replacement Considerations
Distributor notes recommend the DG381 series as an alternative. Verify pin compatibility and electrical specifications before substitution. No other direct cross-reference part numbers are confirmed in the provided source material.
