DG411DVZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411DVZ-T is a monolithic CMOS analog switch manufactured by Renesas Electronics Corporation, housed in a 16-pin TSSOP package. It integrates four independent single-pole single-throw (SPST) switches with TTL and CMOS compatible digital inputs. The device features a maximum on-resistance of 35 ohms and operates within a supply voltage range of 5V to 44V for single supplies, or ±5V to ±20V for dual supplies. Key electrical parameters include a maximum turn-on time of 175ns, a maximum turn-off time of 145ns, and a maximum power supply current of 1µA. It supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific manufacturer source, as the DG411 series has been produced by both Renesas Electronics and Vishay Siliconix. Confirm that the datasheet specifications match the required operational parameters, particularly regarding on-resistance and switching times, before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a drop-in replacement for the DG211 or DG212 series is required. Ensure the application logic matches the non-inverting control scheme, as the DG411 differs from the DG412 only in selection logic polarity. Verify that the 35Ω on-resistance meets the signal integrity requirements of the target circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG411 series serves as a direct upgrade to the legacy DG211 and DG212 devices. It offers improved performance metrics, including lower on-resistance and faster switching speeds, while maintaining compatibility with standard digital logic families. This series is designed for applications requiring reliable analog signal routing with minimal distortion.

DG412DYZ-T: Functionally identical but utilizes positive logic for switch selection instead of the negative logic found in the DG411.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the DG411 differ from the DG412?

The DG411 and DG412 are electrically identical except for the polarity of their selection logic. The DG411 uses negative logic where a logic 0 turns the switch ON, whereas the DG412 uses positive logic.

What is the maximum voltage range for controlling signals?

The device supports a maximum voltage range of 44V, which permits the control of 40V peak-to-peak signals.

Is the DG411 suitable for replacing DG211 devices?

Yes, the DG411 series is explicitly designed as a drop-in replacement for the popular DG211 and DG212 series devices, offering improved on-resistance and switching speed.
