Overview
The DG418BDY-T1-E3 is a precision monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix. It operates within a temperature range of -40 °C to +85 °C and utilizes an SOIC-8 surface-mount package. The device supports dual supply voltages up to ±15 V or single supplies up to 12 V, providing a wide dynamic signal range. Key electrical parameters include a maximum on-resistance (RDS(on)) of 25 Ω at room temperature and 29 Ω across the full temperature range. Turn-on time is specified at a maximum of 89 ns, with a turn-off time of 80 ns under standard test conditions.
Feature Summary
- High-performance switching capability utilizing high voltage silicon gate process technology
- Low power consumption combined with low leakage currents for efficient board space usage
- TTL and CMOS logic compatibility for simple interfacing in various control systems
Applications
- Precision test equipment
- Battery powered industrial and military systems
- Sample-and-hold circuits
- Guidance and control systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing lot traceability requirements. Ensure storage conditions adhere to moisture sensitivity level guidelines prior to soldering. Validate that the ordering suffix matches the required tape and reel packaging configuration for automated assembly processes.
Selection Notes
Select this component when a quad SPST configuration is required within a compact SOIC-8 footprint. The DG418B offers opposite control logic compared to the DG417B; verify truth table alignment with system design. Consider the 25 Ω on-resistance limit for signal integrity requirements. Ensure supply voltage ranges accommodate the intended analog signal swing without exceeding absolute maximum ratings.
Part Context
This part belongs to the DG417B/DG418B/DG419B family of precision analog switches. While sharing similar architecture and performance characteristics, the DG418B is distinguished by its specific logic polarity relative to the DG417B. The DG419B variant introduces break-before-make functionality in an SPDT configuration. All variants utilize the same HVSG process technology for high-voltage handling.
Replacement Considerations
DG417BDY-T1-E3: Functionally identical but features inverted logic control levels compared to the DG418B. Verify truth table compatibility before substitution. DG419BDY-T1-E3: Offers SPDT configuration with break-before-make timing; requires different pinout utilization and does not provide four independent SPST channels.
