DG643DY-T1

Overview

The DG643DY-T1 is a video switch integrated circuit manufactured by Vishay Siliconix, featuring a dual single-pole double-throw (SPDT) configuration. It operates within a supply voltage range of 10 V to 21 V and supports a maximum operating temperature of +85 °C. The device exhibits a maximum on-resistance of 15 Ohms and a bandwidth of 500 MHz. Switching performance includes a maximum turn-on time of 70 ns and a maximum turn-off time of 50 ns. It is housed in a 16-pin SOIC-Narrow package with a power dissipation rating of 600 mW.

Feature Summary

Dual SPDT switching architecture designed for video signal routing applications
High-frequency bandwidth capability supporting wideband signal transmission
Low on-resistance characteristic ensuring minimal signal attenuation

Applications

Video signal multiplexing and distribution systems
Test and measurement equipment requiring high-speed analog switching
Communication infrastructure signal path selection

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific tape-and-reel packaging specifications prior to order placement. Ensure the procurement source provides valid traceability documentation matching the Vishay Siliconix part number DG643DY-T1.

Selection Notes

Select this component when dual independent SPDT switching is required for video frequency signals. Evaluate the 15 Ohm on-resistance against system insertion loss requirements. Confirm that the 10 V to 21 V single-supply operation aligns with the target circuit design constraints and thermal management capabilities.

Part Context

This part belongs to the DG64x series of video switches from Vishay Siliconix. It shares functional similarities with other devices in the family but is distinguished by its specific dual SPDT topology and narrow SOIC packaging. The suffix T1 indicates reel packaging configuration.
