Overview
The DG417LDY-E3 is a high-speed analog switch IC manufactured by Vishay Siliconix, housed in a 16-lead SOIC surface-mount package. It features four independent single-pole single-throw (SPST) channels with a maximum on-resistance of 35 Ohms. The device supports dual supply voltages ranging from 15 V to 15 V and operates within an ambient temperature range of -40°C to +85°C. Key electrical specifications include a maximum propagation delay of 105 ns, turn-on and turn-off times of 105 ns each, and a power dissipation rating of 600 mW. The component draws a maximum supply current of 1 uA and handles a DC switch current of 30 mA.
Feature Summary
- Four-channel SPST configuration for independent signal routing
- High-speed switching performance with 105 ns transition times
- Low power consumption with 1 uA maximum supply current
- Robust thermal handling with 600 mW power dissipation capability
Applications
- Data acquisition systems requiring multi-channel signal selection
- Industrial process control instrumentation
- Medical equipment signal conditioning circuits
Procurement Notes
Verify the specific suffix E3 confirms RoHS compliance status through official manufacturer documentation before integration. Confirm that the SOIC-16 package dimensions match the target PCB footprint requirements. Check for any recent product change notices or end-of-life announcements directly from Vishay Siliconix to ensure long-term availability for production planning.
Selection Notes
Select this component when a quad SPST topology is required with moderate speed and low leakage characteristics. Ensure the application voltage does not exceed the specified 15 V dual supply limit. Consider the 35 Ohm on-resistance impact on signal integrity for precision applications. Verify that the 600 mW power dissipation rating accommodates the thermal design constraints of the final enclosure.
Part Context
This part belongs to the DG series of analog switches from Vishay Siliconix, designed for general-purpose signal switching applications. The DG417 variant specifically offers a quad SPST configuration, distinguishing it from multiplexer or SPDT variants within the same family. It serves as a standard solution for isolating or connecting multiple analog signals in electronic systems.
Replacement Considerations
