DG387BDJ

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.

Analog Switches, Multiplexers, Demultiplexers 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.
