DG411LDY-T1-E3

Overview

The DG411LDY-T1-E3 is a precision monolithic quad single-pole single-throw (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 a maximum drain-source on-resistance of 33 Ω at ±5 V and typical turn-on/turn-off times of 50 ns and 35 ns, respectively. It utilizes BiCMOS technology for improved performance over standard counterparts, offering low leakage current of 0.25 nA and high off-isolation. The component is housed in a 16-pin narrow SOIC package with an operating temperature range of -40 °C to +85 °C.

Feature Summary

• BiCMOS wafer fabrication technology enables operation across wide dynamic ranges with minimal signal errors and distortion.
• Break-before-make switching action prevents signal overlap during channel transitions.
• TTL and CMOS logic compatibility allows for simple interfacing with standard digital control circuits.
• Internal diode clamping protects against input signals exceeding supply rails.

Applications

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

Procurement Notes

Verify the specific suffix configuration when ordering. The 'DY' indicates a 16-pin narrow SOIC package, while 'T1' denotes tape and reel packaging. The '-E3' suffix confirms lead-free plating compliant with RoHS directives. Confirm that the required voltage range aligns with the low-voltage specifications of the L-series rather than the higher voltage DG411 variants.

Selection Notes

Select this component for applications requiring low-voltage operation between 2.7 V and 12 V. Ensure the system logic levels match the specified thresholds of 0.8 V for Logic 0 and 2.4 V for Logic 1. Consider the 33 Ω on-resistance limit at ±5 V dual supply when designing for signal integrity. Verify that the 16-pin SOIC footprint matches the PCB layout requirements.

Part Context

This part belongs to the DG411L, DG412L, and DG413L family of low-voltage analog switches. These devices are pin-for-pin compatible companion devices to the industry-standard DG411, DG412, and DG413 series but utilize BiCMOS technology for enhanced speed and lower resistance. The DG411L specifically provides four independent SPST switches with standard logic control.

Replacement Considerations

DG411LDY-E3: Same functional specifications and package, available in tube packaging instead of tape and reel.

FAQ

How does the DG411L differ from the standard DG411?

The DG411L uses BiCMOS technology allowing operation at lower voltages (2.7 V to 12 V single supply) compared to the standard DG411. It also offers faster switching speeds and lower on-resistance.

What is the break-before-make time delay?

The break-before-make time delay is guaranteed by design at 6 ns. This feature ensures one switch opens before another closes, preventing signal shorting.

Are inputs protected against overvoltage?

Yes, internal diodes clamp signals on Sx, Dx, or INx that exceed V+ or V-. The forward diode current must be limited to the maximum current ratings.
