Overview
The DG643DJ-E3 is a dual SPDT video switch IC manufactured by Vishay Siliconix, housed in a 16-pin PDIP package. It features a maximum on-resistance of 15 ohms and a -3dB bandwidth of 500 MHz. The device operates with supply voltages ranging from 3V to 15V (single) or ±3V to ±15V (dual). Switching times are specified at a maximum of 70 ns for turn-on and 50 ns for turn-off. It supports an operating temperature range from -40°C to +85°C and includes charge injection of 19 pC.
Feature Summary
- Dual single-pole double-throw configuration for signal routing
- High-speed switching capability suitable for video applications
- CMOS logic compatibility for control interfaces
Applications
- Video signal switching and routing
- Data acquisition systems
- Communication equipment
Procurement Notes
Verify component authenticity through authorized distributors as the part status is listed as obsolete. Confirm RoHS compliance details and check for alternative sources due to limited availability. Ensure the 16-PDIP package matches the design requirements before procurement.
Selection Notes
Select this component when dual SPDT switching with high bandwidth is required. Compare on-resistance and leakage current specifications against system needs. Consider the PDIP package constraints for PCB layout and thermal management within the specified temperature range.
Part Context
This part belongs to the DG64x series of analog switches. It shares functional similarities with other Vishay video switches but differs in pin count and configuration. The DG643 specifically offers two independent SPDT channels in a single package.
Replacement Considerations
Check for direct pin-compatible replacements within the Vishay DG series. Verify electrical parameters such as on-resistance and bandwidth match the original design requirements when selecting substitutes.
