Overview
The DG417LDY-T1-E3 is a single-channel Single Pole Single Throw (SPST) analog switch manufactured by Vishay Siliconix. It operates with dual supply voltages ranging from ±15 V to ±20 V or a single supply up to 30 V. The device features a maximum on-resistance of 18.5 Ohms and supports a continuous DC switch current of 30 mA. Key timing parameters include a maximum turn-on time of 41 ns and a maximum turn-off time of 32 ns. It is housed in an MSOP-8 surface-mount package with a power dissipation rating of 320 mW and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Single-channel SPST configuration for signal routing
- Low on-resistance for minimal signal attenuation
- Compatible with standard CMOS logic levels
Applications
- Data acquisition systems
- Industrial process control
- Communications equipment
Procurement Notes
Verify the specific suffix T1 indicates reel packaging when sourcing. Confirm RoHS compliance status via the manufacturer datasheet, as historical variants may differ. Check current lifecycle status, as this component has been superseded by the DG417LDQ-T1-E3 variant in some distribution channels. Ensure the supplier provides valid traceability documentation for quality assurance purposes.
Selection Notes
Select this component for applications requiring a single analog switch with moderate speed and low on-resistance. Compare against the DG417BDY-E3 for SOIC-8 packaging alternatives. Consider the DG417LDQ-T1-E3 if tape-and-reel handling is preferred over tube packaging. Verify voltage requirements align with the ±15 V to ±20 V operating range before integration.
Part Context
This part belongs to the DG41x series of enhanced analog switches from Vishay Siliconix. The series is characterized by improved operating voltage ranges and lower leakage limits compared to earlier generations. The DG417 specifically denotes the single-channel SPST configuration within this family, designed for general-purpose signal switching tasks.
Replacement Considerations
The DG417LDQ-T1-E3 is listed as a recommended alternative with identical electrical specifications but utilizes tape-and-reel packaging instead of tubes. Verify pinout compatibility during substitution.
