Overview
The DG641DY-T1-E3 is a video switch integrated circuit manufactured by Vishay / Siliconix, featuring a configuration of four single-pole single-throw (SPST) switches. It operates on a single supply voltage ranging from 10 V to 21 V, with a typical operating voltage of 15 V and a maximum switch voltage of 8 V. The device delivers a bandwidth of 500 MHz, with a maximum turn-on time of 70 ns and a maximum turn-off time of 50 ns. The maximum on-resistance is 15 Ohms, and the typical off-isolation is -60 dB. Power dissipation is rated at 600 mW. It functions within an operating temperature range of -40°C to +85°C and is housed in a surface-mount SOIC-16 package.
Feature Summary
- High-speed switching capability with 500 MHz bandwidth for video signal applications
- Low on-resistance of 15 Ohms maximum for minimal signal loss
- CMOS logic compatibility with simple interface requirements
- Robust performance with high off-isolation of -60 dB
Applications
- Video signal routing and switching
- Data acquisition systems
- Communication equipment
- Test and measurement instruments
Procurement Notes
Verify the exact part number suffix, as the source data lists DG641DY-T1-E3. Confirm availability status, as the component is marked as obsolete or not sold in certain regions. Check RoHS compliance details directly from the manufacturer's documentation before procurement.
Selection Notes
Select this component when high-speed video switching is required with low on-resistance. Ensure the design supports a single supply voltage between 10 V and 21 V. Verify that the SOIC-16 package fits the PCB layout constraints and that the operating temperature range meets environmental requirements.
Part Context
This part belongs to the DG series of analog and video switches from Vishay / Siliconix. It is designed for precision switching applications requiring fast response times and low distortion. The DG641 variant specifically targets video frequency signals, offering higher bandwidth compared to standard analog switches in the same family.
Replacement Considerations
Publicly documented recommended alternatives include parts from the DG61 series. Verify pinout compatibility and electrical specifications such as on-resistance and bandwidth when substituting.
