DG412HSDY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG412HSDY is a precision monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix. It features four independent switches in a 16-pin Narrow SOIC package, designed for high-speed switching of precision analog signals with low power consumption. The device operates on dual supplies ranging from ±5 V to ±20 V or single supplies up to 44 V. Key electrical parameters include a maximum on-resistance of 35 Ω at room temperature, a turn-on time of 105 ns, and a turn-off time of 80 ns under standard test conditions. It supports an analog signal range of ±15 V and exhibits ultra-low power dissipation of 0.35 µW.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and environmental compliance. The 'DY' suffix indicates a 16-pin Narrow SOIC package. Confirm RoHS status as non-compliant variants may exist without the '-E3' designation. Check lead availability and lifecycle status directly with authorized distributors, as production schedules can change without notice.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG412HSDY when break-before-make timing is required to prevent signal overlap. Ensure the application voltage does not exceed the 44 V absolute maximum rating between V+ and V-. Verify that the logic input levels are compatible with the VL pin voltage. Consider thermal derating requirements if operating above 75 °C, as power dissipation limits decrease significantly at higher temperatures.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG412HSDY belongs to the DG411HS/DG412HS/DG413HS series of precision analog switches. Unlike the DG411HS which uses positive logic, the DG412HS utilizes inverted control logic where a logic low turns the switch on. The DG413HS variant combines both normally open and normally closed switches. This family is built on a high-voltage silicon gate process optimized for low error and high speed.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG411HSDY: Identical package and specifications but uses positive logic control (Logic High = ON). DG412HSDN-T1-E4: Same electrical characteristics but housed in a 16-QFN package instead of SOIC-16. DG412LEDY-T1-GE3: Lower voltage rating (±8 V max) and different switching speeds; verify compatibility before substitution.
