Overview
The DG419LDY-T1-E3 is a single-channel SPDT analog switch IC manufactured by Vishay Siliconix. It operates with dual supply voltages ranging from -15 V to +15 V and supports single supplies up to 30 V. The device features a maximum on-resistance of 18.5 Ohms, ensuring low signal distortion in switching applications. Key timing parameters include a maximum turn-on time of 41 ns and a maximum turn-off time of 32 ns. It functions within an industrial temperature range of -40°C to +85°C. Power dissipation is rated at 400 mW, with a maximum supply current of 1 µA. The component is housed in an SOIC-8 surface-mount package.
Feature Summary
- Single-pole double-throw (SPDT) configuration for precise signal routing
- Low power consumption suitable for battery-operated systems
- Industrial temperature range operation for robust environmental performance
Applications
- Data acquisition systems requiring signal multiplexing
- Instrumentation circuits needing isolated signal paths
- Communication equipment for channel selection
Procurement Notes
Verify the specific suffix T1-E3 against official Vishay documentation to confirm RoHS compliance and tape-and-reel packaging specifications. Confirm that the part number matches the exact electrical characteristics required for the design, as variations exist within the DG419 family. Cross-reference with authorized distributors to ensure authenticity and traceability.
Selection Notes
Select this component when a single SPDT switch with moderate speed and low on-resistance is required. Compare against the DG419DY-E3 for tube packaging alternatives or the DG419LEDY-T1-GE4 if lower voltage operation and reduced on-resistance are prioritized. Ensure the SOIC-8 footprint fits the PCB layout constraints.
Part Context
This part belongs to the DG series of enhanced analog switches from Vishay Siliconix. The series is characterized by improved operating voltage ranges and leakage limits compared to earlier generations. The DG419LDY-T1-E3 specifically targets applications requiring reliable switching in industrial environments with standard dual-supply configurations.
Replacement Considerations
The DG419LDY-E3 is listed as an alias for this part number. The DG419DY-E3 offers identical electrical specifications but utilizes tube packaging instead of tape-and-reel. Verify pin compatibility before substitution.
