Overview
The DG308BDY-T1 is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix in a 16-pin Narrow SOIC package. It operates on dual supplies 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 operating range (-40 °C to +85 °C). Key electrical parameters include a turn-on time of 200 ns, turn-off time of 150 ns, and a charge injection of 1 pC. Supply current is limited to 1 µA, with an off-leakage current of 20 nA.
Feature Summary
- CMOS fabrication process for low power consumption and high speed
- Improved charge injection compensation design minimizes switching transients
- Epitaxial layer prevents latchup under extreme conditions
- True bi-directional signal handling capability
Applications
- Industrial instrumentation
- Test equipment
- Communications systems
- Sample-and-hold circuits
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and tape/reel specifications. Check RoHS compliance status as indicated in ordering information. Ensure storage and handling procedures meet ESD protection standards for CMOS devices.
Selection Notes
Select this part when a quad SPST configuration with low leakage and fast switching is required. Verify that the system voltage does not exceed the ±22 V absolute maximum rating. Consider the 85 Ω on-resistance limit for signal integrity requirements. Ensure logic levels are compatible with the specified input voltage thresholds.
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 on-resistance and higher speed compared to previous generations. The device is designed for telecommunications and process control applications requiring reliable analog signal routing.
Replacement Considerations
DG308A is the predecessor model with higher resistance and slower speeds. DG309B offers the same package but functions as a normally closed switch instead of normally open. Cross-reference pinouts and logic tables carefully when substituting.
