Overview
The DG641DY-E3 is a video switch integrated circuit manufactured by Vishay Siliconix, housed in a 16-pin SOIC surface-mount package. It features four independent single-pole single-throw (SPST) channels designed for high-speed signal routing. The device operates on a single supply voltage ranging from 10 V to 21 V, with a typical operating voltage of 15 V. Key electrical specifications include a maximum on-resistance of 15 Ohms and a -3 dB bandwidth of 500 MHz. Switching performance is characterized by a maximum turn-on time of 70 ns and a maximum turn-off time of 50 ns. The component supports an ambient operating temperature range from -40°C to +85°C and includes a typical off-isolation of -60 dB.
Feature Summary
- Four-channel SPST configuration for multi-signal path management
- High-frequency video signal handling capability
- CMOS logic interface compatibility
Applications
- Video signal switching matrices
- Test and measurement equipment signal routing
- Data acquisition systems
Procurement Notes
Verify the specific suffix E3 against official Vishay documentation to confirm RoHS compliance status. Confirm the package type matches the required SOIC-16 footprint for PCB layout. Check current lifecycle status as distribution data indicates potential discontinuation or limited availability for this specific part number variant.
Selection Notes
Select this component when four isolated SPST switches are required within a single package. Ensure the application voltage stays within the 10 V to 21 V single-supply range. Verify that the 15 Ohm on-resistance meets the signal integrity requirements for the target video frequency applications.
Part Context
This part belongs to the DG64x series of video switches from Vishay Siliconix. It shares functional similarities with other members like the DG642 and DG643 but differs in channel count and configuration. The DG641 specifically provides four SPST channels, whereas other series members may offer multiplexer structures or different channel counts.
Replacement Considerations
Public sources list DG641DY-T1-E3 as a recommended alternative. Verify if the T1 suffix denotes a tape-and-reel packaging variation rather than a functional change. Cross-reference pinouts and electrical parameters with the official datasheet before substitution.
