Overview
The DG387BDJ is a single-channel SPDT analog switch manufactured by Vishay Siliconix. It operates within a supply voltage range of 0 V to 15 V, supporting both single and dual power configurations with a maximum dual supply of ±15 V. The device features a maximum on-resistance of 50 Ohms and supports a DC switch current of 30 mA. Key timing specifications include a maximum turn-on time of 150 ns and a maximum turn-off time of 130 ns. It is housed in a 14-pin PDIP package for through-hole mounting and functions reliably across an operating temperature range of -40 °C to +85 °C.
Feature Summary
- Single-pole double-throw (SPDT) configuration providing one independent signal path
- Low power consumption with a maximum supply current of 1 mA
- Robust thermal performance with a power dissipation rating of 470 mW
Applications
- Signal routing in data acquisition systems
- Multiplexing sensor inputs
- Audio signal switching applications
Procurement Notes
Verify the specific ordering suffix and RoHS compliance status before procurement, as availability may vary. Confirm that the PDIP-14 through-hole package aligns with the target PCB layout requirements. Ensure the selected component meets the required electrical parameters for the intended circuit design.
Selection Notes
Select this component when a single analog channel requires switching between two paths. Verify that the system voltage does not exceed the 15 V maximum limit. Consider the 50 Ohm on-resistance impact on signal integrity for high-precision applications.
Part Context
This part belongs to the DG series of analog switches from Vishay Siliconix. It serves as a discrete solution for basic signal routing tasks where low cost and standard packaging are prioritized over high-speed or multi-channel integration.
Replacement Considerations
Check for direct pin-compatible alternatives within the same Vishay family if stock is limited. Ensure any substitute maintains the 14-pin DIP form factor and similar electrical characteristics.
