DG411DY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411DY is a monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Renesas Electronics Corporation. It features four independent switches with TTL and CMOS compatible digital inputs, serving as a drop-in replacement for the DG211 and DG212 series. The device utilizes a high-voltage silicon-gate process with an epitaxial layer to prevent latch-up. Key electrical parameters include a maximum on-resistance of 35Ω, a maximum turn-on time of 175ns, and a maximum turn-off time of 145ns. It supports single supply voltages from +5V to 44V or split supplies from ±5V to ±20V, allowing control of 40V peak-to-peak signals. Operating temperature ranges from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer origin carefully, as the DG411 part number has been produced by multiple vendors including Vishay Siliconix and Intersil. Confirm that the specific DG411DY suffix corresponds to the intended package type and manufacturing source required for your design. Ensure compliance with RoHS standards if lead-free components are mandated for the assembly process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration with fast switching speeds is required. It is suitable for applications needing wide dynamic range and low signal distortion. Consider the DG412 or DG413 variants if different logic polarities or mixed logic functions are necessary for complex switching topologies.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG411 series represents an upgrade over the older DG211 and DG212 devices, offering improved performance metrics such as lower on-resistance and faster switching times. This evolution allows designers to maintain compatibility with existing layouts while benefiting from enhanced signal integrity and reduced power consumption in modern electronic circuits.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG411 is explicitly documented as a drop-in replacement for the DG211 and DG212 series. Designers can substitute these legacy parts without modifying the board layout or external circuitry, provided the voltage and current ratings remain within the specified limits.
