DG412DY-T

Analog Switches, Multiplexers, Demultiplexers Overview

The DG412DY-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 single supply voltages from +5V to +44V or dual supplies of ±5V to ±20V. Key electrical parameters include a maximum on-resistance of 35 Ohms, a maximum operating speed of 175 ns for turn-on and 145 ns for turn-off, and a maximum power supply current of 1 uA. It operates reliably across a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Includes an epitaxial layer to prevent latch-up associated with older CMOS technologies
• Provides TTL and CMOS compatible digital inputs for flexible logic interfacing

Analog Switches, Multiplexers, Demultiplexers Applications

• Sample-and-hold amplifier circuits
• Data acquisition systems
• Process control signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the manufacturer marking and date code against official Renesas documentation to ensure authenticity. Confirm that the specific suffix matches the required packaging format. Check RoHS compliance status through the manufacturer's environmental declaration. Ensure moisture sensitivity level handling procedures are followed during storage and assembly.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration with low on-resistance is required. Compare specifications against the DG411 series if inverted logic levels are needed instead. Verify that the 44V maximum voltage rating aligns with the system's signal swing requirements. Consider the SOIC-Narrow package dimensions for PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG411/DG412/DG413 family of monolithic CMOS analog switches. These devices serve as drop-in replacements for legacy DG211 and DG212 series components. The DG412 variant specifically utilizes positive logic for switch selection, distinguishing it from the DG411 which uses negative logic.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG411DVZ-T offers identical switching performance but utilizes negative logic for channel selection. DG412DYZ-T provides the same functionality in a different SOIC-16 package variant.
