Overview
The DG308BDY-E3 is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix in a 16-pin Narrow SOIC package. It operates with dual supply voltages ranging from ±4 V to ±22 V or a single supply up to 44 V. The device features a maximum on-resistance of 85 Ω at room temperature and 100 Ω across the full industrial temperature range (-40 °C to +85 °C). Key dynamic parameters include a turn-on time of 200 ns, turn-off time of 150 ns, and charge injection of 1 pC under standard test conditions.
Feature Summary
- CMOS fabrication process ensures low power consumption and compatibility with standard logic levels.
- Epitaxial layer design prevents latch-up for enhanced reliability during signal handling.
- Improved charge injection compensation minimizes switching transients for higher accuracy.
- True bi-directional performance allows signals to pass freely when enabled.
Applications
- Industrial instrumentation signal routing
- Test equipment multiplexing
- Sample-and-hold circuits
- Communications systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation as suffixes may indicate specific environmental certifications. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.
Selection Notes
Select this part for applications requiring quad SPST switching with low on-resistance and fast transition times. Ensure the operating voltage does not exceed ±22 V for continuous operation. Verify that the thermal dissipation requirements fit within the 640 mW package limit at the intended ambient temperature.
Part Context
This component belongs to the DG308B series, representing an improved version of the industry-standard DG308A. It utilizes Vishay Siliconix proprietary silicon gate CMOS technology to achieve lower leakage and higher speed compared to previous generations.
Replacement Considerations
The DG308ADY-E3 serves as a functional substitute within the same family, though it exhibits higher on-resistance (100 Ω typical) compared to the DG308BDY-E3 (85 Ω typical).
