Overview
The DG641DY-T1-E3 is a video switch integrated circuit manufactured by Vishay Siliconix, housed in a 16-pin SOIC surface-mount package. It features four single-pole single-throw (SPST) channels with a maximum on-resistance of 15 Ohms and a bandwidth of 500 MHz. The device operates within a supply voltage range of 10 V to 21 V, supporting a maximum operating voltage of 15 V. Switching performance includes a maximum turn-on time of 70 ns and a maximum turn-off time of 50 ns. It functions reliably across an extended temperature range from -40°C to +85°C, with a typical off-isolation of -60 dB and a power dissipation rating of 600 mW.
Feature Summary
- Four independent SPST analog switches configured for high-speed signal routing
- Wide bandwidth capability suitable for video frequency applications
- Low on-resistance characteristic ensuring minimal signal attenuation
- Single-supply operation simplifying power management requirements
Applications
- Video signal switching and distribution systems
- Data acquisition channel multiplexing
- Test and measurement equipment signal routing
- Communication interface signal gating
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check current lifecycle status as obsolescence may affect long-term availability. Ensure packaging specifications match production requirements.
Selection Notes
Evaluate on-resistance and bandwidth against signal integrity requirements. Verify supply voltage compatibility with system power rails. Consider thermal dissipation limits within the SOIC-16 package. Compare switching speeds with application timing constraints.
Part Context
This component belongs to the DG64x series of video switches from Vishay Siliconix. The series offers multiple configurations for analog signal routing. The DG641 variant specifically provides four SPST channels optimized for video frequencies. It shares design heritage with other DG4xx and DG5xx series devices.
Replacement Considerations
Official datasheets list the DG61 as a recommended alternative. Verify pinout compatibility and electrical parameter equivalence before substitution. Cross-reference specific suffix variations for package and tape-and-reel differences.
