DG412LDY-T1

Overview

The DG412LDY-T1 is a precision monolithic quad SPST low-voltage CMOS analog switch manufactured by Vishay Siliconix. It operates on single supplies from 2.7 V to 12 V or dual supplies from ±3 V to ±6 V. The device features an on-resistance of 17 Ω, turn-on time of 19 ns, and turn-off time of 12 ns. It supports TTL and CMOS logic levels with low leakage current of 0.25 nA and 2000 V ESD protection. Packaged in a 16-pin narrow SOIC, it handles continuous currents up to 30 mA.

Feature Summary

• Low voltage operation compatible with single and dual power supplies
• Fast switching speeds with minimal insertion loss
• TTL and CMOS logic interface compatibility
• High off-isolation and channel-to-channel crosstalk performance

Applications

• Precision automatic test equipment
• Precision data acquisition systems
• Communication systems including DSL and DSLAM
• Audio and video signal routing
• Battery powered portable systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing process. Cross-reference the part number with authorized distributors to confirm availability and authenticity before placing orders.

Selection Notes

Select this component for applications requiring low voltage operation and fast switching times. Consider the DG411L or DG413L if different control logic polarities or normally closed switch configurations are needed. Ensure the supply voltage range matches the system requirements and verify thermal dissipation limits for the chosen package.

Part Context

This part belongs to the DG411L, DG412L, and DG413L family of low-voltage CMOS analog switches. These devices are pin-for-pin compatible with industry standard counterparts but offer improved performance using BiCMOS wafer fabrication technology. They are designed for high-speed signal switching with flat on-resistance over the analog signal range.

FAQ

What is the logic polarity for the DG412L?

The DG412L responds to opposite control logic compared to the DG411L. A logic '0' turns the switch OFF, while a logic '1' turns it ON.

What is the maximum power dissipation for the SOIC package?

The maximum power dissipation for the 16-pin SOIC package is 650 mW at room temperature, derating by 7.6 mW/°C above 75 °C.

Does the DG412L support break-before-make switching?

No, the DG412L does not feature break-before-make switching. This function is only available in the DG413L variant.
