Overview
The DG411LDY is a precision monolithic quad single-pole single-throw (SPST) low-voltage CMOS analog switch manufactured by Vishay Siliconix. It operates on single supplies from 2.7 V to 12 V or dual supplies of ±3 V to ±6 V. The device features an on-resistance of 17 Ω, turn-on time of 19 ns, and turn-off time of 12 ns. It supports TTL and CMOS logic inputs with low leakage current of 0.25 nA and provides 2000 V ESD protection. Power dissipation in the 16-pin narrow SOIC package is rated at 650 mW.
Feature Summary
- Low voltage operation compatible with single and dual power supplies
- Fast switching speeds with minimal insertion loss for signal integrity
- TTL and CMOS logic compatibility for simple interfacing
- Break-before-make switching action prevents signal shorting
Applications
- Precision automatic test equipment
- Audio and video signal routing
- DSL and DSLAM systems
- Battery powered systems
Procurement Notes
Verify the specific suffix against the datasheet ordering information to confirm package type and RoHS compliance status. Confirm that the component meets the required operating temperature range of -40 °C to +85 °C. Ensure supply voltages remain within the absolute maximum ratings to prevent permanent damage.
Selection Notes
Select this component when low voltage operation and high-speed switching are required. Compare the 17 Ω on-resistance against system requirements. Verify logic level compatibility with the control circuitry. Consider the 16-pin SOIC package dimensions for PCB layout constraints.
Part Context
The DG411LDY belongs to the DG411L series, which serves as a low-voltage companion to the industry-standard DG411 series. It utilizes BiCMOS wafer fabrication technology to achieve improved performance characteristics while maintaining pin-for-pin compatibility with legacy designs.

FAQ
What is the logic sense for the DG411LDY?
Logic '0' (≤ 0.8 V) turns the switch OFF, and Logic '1' (≥ 2.4 V) turns the switch ON.
Does the DG411LDY support break-before-make switching?
No, break-before-make switching is a feature specific to the DG413L variant within the same family.
What is the maximum power dissipation for the DG411LDY?
The maximum power dissipation is 650 mW for the 16-pin narrow SOIC package.
