Overview
The DG308BDY-T1-E3 is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates with dual supply voltages ranging from ±4 V to ±22 V or a single supply from 4 V to 44 V. The device features a maximum on-resistance of 85 Ω at room temperature and up to 100 Ω across the full operating range. Switching times are specified with a maximum turn-on time of 200 ns and a turn-off time of 150 ns under dual supply conditions. Power consumption is low, with supply currents typically around 1 µA. The component is housed in a 16-pin Narrow SOIC package and supports an extended industrial temperature range from -40 °C to +85 °C.
Feature Summary
- CMOS fabrication process for low power consumption and high speed
- Improved charge injection compensation design minimizes switching transients
- Epitaxial layer prevents latchup for reliable operation
- True bi-directional signal handling capability
Applications
- Industrial instrumentation
- Test equipment
- Sample-and-hold circuits
- Communications systems
Procurement Notes
Verify the specific suffix T1-E3 against the official datasheet to confirm the tape-and-reel packaging format and lead-free compliance status. Ensure the ordering code matches the exact Vishay part number to avoid discrepancies in package type or environmental certification during procurement.
Selection Notes
Select this component when a normally open quad SPST configuration is required within the DG308B family. Compare the 85 Ω on-resistance and 200 ns switching speed against alternative models like the DG211 if lower resistance or different logic thresholds are needed for the specific circuit application.
Part Context
This part belongs to the DG308B series, which represents improved versions of the industry-standard DG308A. Manufactured using Vishay's proprietary silicon gate CMOS process, it offers enhanced performance characteristics including lower leakage current and higher switching speeds compared to previous generations.
Replacement Considerations
The DG308BDJ-E3 serves as a direct pin-compatible replacement in a 16-pin DIP package. For applications requiring normally closed switches, the DG309BDY-T1-E3 is the functional counterpart within the same series.
