DG201BDK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201BDK is a quad single-pole single-throw (SPST) analog switch IC manufactured by Vishay Siliconix. It features four independent channels in a 16-pin Ceramic Dual In-Line Package (CDIP). The device supports single or dual power supplies, with a maximum on-resistance of 85 Ohms and a maximum switching current of 30 mA. Operating voltage ranges from 0 V to 12 V for single supply and 4.5 V to 22 V for dual supply. Switching times are specified at a maximum of 300 ns for turn-on and 200 ns for turn-off. The component operates within a temperature range of -40°C to +85°C and has a maximum power dissipation of 640 mW.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix and package variant when sourcing, as the DG201 series includes plastic and ceramic options. Confirm RoHS compliance status, as older ceramic packages may not meet current environmental directives. Check lead times carefully due to potential obsolescence or limited production runs for legacy DIP components. Ensure the supplier provides original manufacturer documentation to verify authenticity and lot traceability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high reliability and hermetic sealing are required, as indicated by the ceramic package. Compare on-resistance and leakage specifications against other DG series variants if lower resistance is needed. Consider the physical size constraints of the 16-CDIP package versus surface-mount alternatives like TSSOP. Verify that the 85 Ohm on-resistance meets the signal integrity requirements of the target application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG201BDK belongs to the DG series of analog switches from Vishay Siliconix, designed for general-purpose signal switching. It is part of a family that includes various configurations such as SPDT and multiplexers. The BDK suffix specifically denotes the 16-lead ceramic dual in-line package, distinguishing it from plastic versions like the DG201BQ. This series is known for robust performance in harsh environments.
