Overview
The DG643DJ is a dual SPDT video switch IC manufactured by Vishay Siliconix, housed in a 16-pin Plastic DIP package. It features a maximum on-resistance of 15 ohms and a -3dB bandwidth of 500 MHz. The device supports single supply voltages from 3V to 15V or dual supplies from ±3V to ±15V. Switching times are specified with a maximum turn-on time of 70 ns and a maximum turn-off time of 50 ns. Operating temperature range spans from -40°C to +85°C.
Feature Summary
- Dual SPDT configuration for signal routing
- Wideband performance up to 500 MHz
- TTL logic compatible control inputs
- Fast switching speeds with low charge injection
Applications
- RF and video switching
- RGB switching
- Video routing
- Programmable filters
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package type and compliance standards. Check current production status as availability may vary. Ensure proper handling procedures are followed during installation to maintain device integrity.
Selection Notes
Select this component when dual independent SPDT switching is required within a wide bandwidth application. Verify that the 16-pin DIP package fits the PCB layout constraints. Ensure the power supply voltage range aligns with the system design requirements. Consider thermal dissipation limits if operating at elevated temperatures.
Part Context
This part belongs to the DG641/DG642/DG643 family of low on-resistance wideband video switches. The DG643 specifically provides two SPDT switches, whereas the DG641 offers four SPST switches and the DG642 provides one SPDT switch. All share similar D/CMOS process technology and electrical characteristics.
Replacement Considerations
DG643DY-E3 is a surface mount alternative in SOIC-16 package. DG643DJ-E3 is the RoHS-compliant version of the same DIP package. Verify pinout compatibility and electrical specifications before substitution.
