DG412HSDY

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.

Feature Summary

• High-voltage silico gate process construction prevents latchup and ensures superior switching performance.
• Break-before-make switching action minimizes signal glitches during channel transitions.
• TTL and CMOS logic compatibility allows for simple interfacing with digital control systems.
• Single supply capability provides flexibility in system design and power management.

Applications

• Precision automatic test equipment
• Precision data acquisition systems
• Communication systems
• Battery powered industrial and military applications

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.

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.

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.

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.
