Overview
The DG442DJ-E3 is a quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It features a normally open configuration and operates on dual supplies ranging from ±5 V to ±11 V, or a single supply from 10 V to 22 V. The device provides a typical drain-source on-resistance of 50 Ω with a maximum of 85 Ω at room temperature under dual supply conditions. Turn-on time is typically 150 ns, reaching a maximum of 250 ns. It supports an analog signal range equal to the supply rails and includes TTL/CMOS-compatible logic inputs.
Feature Summary
- High-speed switching with minimized charge injection for sample-and-hold applications
- TTL and CMOS compatible logic interface for simplified system integration
- Epitaxial layer construction prevents latchup and ensures high voltage ratings
Applications
- Sample-and-hold circuits
- Data acquisition systems
- Audio switching
- Automatic test equipment
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the presence of the -E3 suffix to ensure compliance with current material categorization standards. Validate that the package matches the specified 16-pin plastic DIP form factor before finalizing procurement orders.
Selection Notes
Select this part when a normally open SPST configuration is required for upgrading legacy DG201A/DG202 sockets. Ensure the application voltage does not exceed the absolute maximum ratings of 44 V between V+ and V-. Verify that the 85 Ω maximum on-resistance meets the specific signal integrity requirements of the target circuit design.
Part Context
This component belongs to the DG44x series of monolithic quad analog switches designed for low error switching of analog and audio signals. The DG442 variant specifically provides a normally open function, contrasting with the DG441's normally closed operation. Both share identical pinouts and electrical characteristics within the same family.
Replacement Considerations
The DG441DJ-E3 serves as a functional alternative if a normally closed configuration is acceptable. For socket upgrades, the DG201A and DG202 are referenced in documentation as legacy counterparts, though they may require distinct power supply considerations.
