Overview
The DG442BDY-T1-E3 is a monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix. It features a typical on-resistance of 45 Ω and fast switching times with a maximum turn-on time of 220 ns and turn-off time of 120 ns under dual supply conditions. The device operates with single supplies from 12 V to 36 V or dual supplies ranging from ±7 V to ±22 V. It utilizes a high-voltage silicon-gate process with an epitaxial layer to prevent latchup, ensuring low power consumption of 1 mW and minimal charge injection.
Feature Summary
- Low on-resistance for reduced signal errors and distortion
- Fast switching action for faster system throughput
- Minimized charge injection suitable for sample-and-hold circuits
- TTL/CMOS-compatible logic for simple interfacing
Applications
- Audio switching
- Data acquisition systems
- Sample-and-hold circuits
- Communication systems
- Automatic test equipment
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives as indicated in the official datasheet. Confirm that the component meets the required operating temperature range of -40 °C to +85 °C for the intended application environment before finalizing procurement.
Selection Notes
Select this component when low on-resistance and high-speed switching are critical requirements. The DG442B variant provides normally closed functionality compared to the DG441B. Consider the single-supply capability if power supply constraints exist. Verify that the logic input voltage levels align with the system's control signals to ensure proper switching thresholds.
Part Context
The DG442BDY-T1-E3 belongs to the DG441B/DG442B family, which are upgraded versions of the original DG441 and DG442 switches. These devices are designed for high-speed, low-error switching of analog and audio signals. The 'BDY' designation indicates a 16-pin Narrow SOIC package, while the '-T1' suffix typically denotes tape and reel packaging for automated assembly.
Replacement Considerations
The DG441BDY-T1-E3 is a functional alternative within the same family, differing primarily in switch state configuration (normally open vs. normally closed). Verify pin compatibility and logic truth table differences before substitution.
