DG643DY is listed in the Analog Switches, Multiplexers, Demultiplexers range at ChipApex. The manufacturer field lists Vishay Siliconix. Its product description is IC SWITCH SPDT X 2 15OHM 16SOIC. Review the specifications below when checking this part for your BOM.
The DG643DY is a dual single-pole double-throw (SPDT) video switch IC manufactured by Vishay Siliconix in a 16-pin narrow SOIC package. It features a wide bandwidth of 500 MHz and low on-resistance with a maximum value of 15 Ohms. The device supports operation from a single supply voltage ranging from 10 V to 21 V, or dual supplies up to ±15 V. Key dynamic characteristics include a maximum turn-on time of 70 ns and a maximum turn-off time of 50 ns. It operates within a temperature range of -40 °C to +85 °C and offers high off-isolation.
Verify the specific ordering suffix against current manufacturer documentation to confirm package type and environmental compliance. Confirm availability status as distribution channels may vary. Ensure the selected component matches the required pinout and thermal specifications for the target PCB layout.
Select this component when a dual-channel SPDT topology is required for video or RF applications. Verify that the 15 Ohm maximum on-resistance meets system insertion loss requirements. Ensure the power supply architecture supports the specified voltage ranges and that decoupling capacitors are placed close to the V+ and V- pins to maintain stability.
The DG643DY belongs to the DG641/DG642/DG643 series of low on-resistance wideband video switches. While the DG641 provides four SPST channels and the DG642 offers a single SPDT channel, the DG643 specifically integrates two independent SPDT switches into one monolithic die, optimizing board space for multi-channel routing tasks.
