DG411LDQ-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG411LDQ-T1 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 and fast switching times with a turn-on time of 50 ns and a turn-off time of 35 ns at room temperature under standard test conditions. It utilizes BiCMOS wafer fabrication technology for improved performance over legacy devices, offering minimal insertion loss and excellent crosstalk characteristics.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T1' indicates tape and reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation as ordering suffixes may affect environmental certifications. Ensure the procurement channel provides valid traceability for the Vishay Siliconix manufacturing origin.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low-voltage analog signal switching with high speed. Verify that the required supply voltage falls within the 2.7 V to 12 V single or ±3 V to ±6 V dual range. Consider the TSSOP-16 package dimensions for PCB layout constraints and ensure thermal dissipation requirements are met within the specified operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG411L family, which serves as a low-voltage companion to the industry-standard DG411 series. It shares pin compatibility while offering enhanced performance through BiCMOS technology. The 'DQ' designation specifies the 16-pin TSSOP package, and the '-T1' suffix denotes the reel packaging format for automated assembly.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic control configuration for the DG411L?

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

Does the DG411L support break-before-make switching?

No, the DG411L does not feature break-before-make switching. This function is available in the companion DG413L model.

What is the maximum analog signal range for the DG411L?

The analog signal range extends from the negative supply rail (V-) to the positive supply rail (V+), allowing full dynamic range operation within the specified supply limits.
