DG441DY-T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG441DY-T is a monolithic CMOS analog switch manufactured by Renesas Electronics Corporation. It integrates four independent single-pole single-throw (SPST) switches within a 16-pin SOIC-Narrow package. The device supports dual power supplies ranging from ±5 V to ±20 V or a single supply from 5 V to 34 V. Key electrical specifications include a maximum on-resistance of 85 Ohms, a maximum switching time of 250 ns, and an off-time of 120 ns. The component operates within a temperature range of -40°C to +85°C and features a maximum power dissipation of 696 mW.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer designation carefully, as the DG441 series has been produced by Analog Devices/Maxim Integrated, Vishay/Siliconix, and Renesas/Intersil. Confirm that the specific suffix matches the required datasheet version and pinout compatibility. Ensure the ordering information aligns with the current Renesas product portfolio status.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required with moderate on-resistance. Verify that the 85 Ohm on-resistance meets the application's voltage drop requirements. Ensure the operating voltage range fits within the specified 5 V to 34 V limits. Consider the 16-pin SOIC-Narrow package dimensions for PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG441 family of improved quad SPST analog switches. It serves as a successor to earlier CMOS switch technologies, offering enhanced performance characteristics such as reduced charge injection and latch-up immunity. The device is designed for applications requiring reliable analog signal switching in industrial and commercial environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG441DYZ-T is a verified equivalent variant offered by Renesas/Intersil. Both parts share identical electrical specifications and functionality. The primary distinction lies in the packaging; the DYZ variant utilizes a TSSOP-16 package instead of the SOIC-Narrow-16 form factor.
