Overview
The DG441DY-T1-E3 is a monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix in a 16-pin narrow SOIC package. It features a typical drain-source on-resistance of 50 Ω and a maximum turn-on time of 250 ns under dual supply conditions (±15 V). The device supports single supplies from 5 V to 36 V or dual supplies from ±5 V to ±22 V. Key electrical parameters include a maximum leakage current of 0.5 nA, charge injection of 1 pC, and a power dissipation rating of 900 mW for the SOIC package.
Feature Summary
- Designed for high-speed switching of analog and audio signals with minimized charge injection.
- Built on a high-voltage silicon-gate process with an epitaxial layer to prevent latchup.
- Features TTL/CMOS-compatible logic inputs for simple interfacing.
Applications
- Audio switching
- Data acquisition systems
- Sample-and-hold circuits
- Automatic test equipment
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and tape/reel specifications. Ensure that the component meets RoHS compliance requirements as defined in the manufacturer's material categorization guidelines before finalizing procurement orders.
Selection Notes
Select this component when upgrading legacy DG201A/DG202 sockets or requiring low signal distortion. Consider the 50 Ω typical on-resistance and 250 ns maximum switching speed for timing constraints. Verify that the operating voltage range aligns with the system's single or dual supply architecture.
Part Context
This part belongs to the DG441/DG442 family of quad SPST analog switches. The DG441 variant specifically provides a normally closed function, distinguishing it from the DG442 which offers a normally open configuration. Both share identical pinouts and core performance characteristics.

FAQ
What is the default state of the DG441 switches?
The DG441 switches are designed with a normally closed function, meaning they conduct when the logic input is low.
How does the DG441 handle input voltages exceeding supply levels?
Signals on the source or drain pins exceeding the supply levels will be clamped by internal diodes.
Is the DG441 suitable for sample-and-hold applications?
Yes, the device is specifically designed with minimized charge injection on the drain to support sample-and-hold circuit requirements.
