DG412LEDQ-T1-GE3

Overview

The DG412LEDQ-T1-GE3 is a monolithic quad single-pole-single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates on single supplies from 3 V to 16 V or dual supplies of ±3 V to ±8 V. The device features a typical drain-source on-resistance of 16 Ω, low parasitic capacitance with CD(on) at 15 pF and CS(off) at 5 pF, and charge injection below 8 pC. Switching times are fast, with tON at 16 ns and tOFF at 9 ns. It is housed in a 16-lead TSSOP package and supports TTL and CMOS compatible logic inputs.

Feature Summary

• Low on-resistance of 16 Ω for minimal signal loss
• Fast switching action with turn-on time of 16 ns
• Low parasitic capacitance and charge injection under 8 pC
• Compatible with TTL and CMOS digital logic levels

Applications

• Automatic test equipment
• Data acquisition systems
• Medical and healthcare systems
• Audio and video signal routing
• Battery powered systems

Procurement Notes

Verify the specific ordering suffix 'DQ' corresponds to the 16-pin TSSOP package configuration before procurement. Confirm that the 'T1' suffix indicates tape and reel packaging containing 3000 units per order quantity. Ensure compliance requirements match the 'GE3' designation for lead-free and RoHS standards as specified in the manufacturer's documentation.

Selection Notes

Select this component when low on-resistance and fast switching speeds are required for precision analog signal routing. The DG412LE variant utilizes positive logic control, distinguishing it from the DG411LE which uses negative logic. Ensure the application voltage range falls within the 3 V to 16 V single supply or ±3 V to ±8 V dual supply limits to maintain optimal performance characteristics.

Part Context

This part belongs to the DG411LE/DG412LE/DG413LE family of low-voltage quad SPST switches. While functionally similar to the DG411LE, the DG412LE differs specifically in its logic polarity response. The DG413LE offers mixed normally open and closed configurations. All variants share identical electrical specifications regarding resistance, capacitance, and switching speeds.

FAQ

How does the logic control of the DG412LE differ from the DG411LE?

The DG412LE and DG411LE respond to opposite logic levels; a logic high turns the DG412LE on, whereas a logic low turns the DG411LE on.

What is the maximum recommended dual supply voltage for this device?

Dual supply operation is recommended up to ±8 V, allowing for a total supply span of 16 V.

Does the DG412LEDQ-T1-GE3 support break-before-make switching?

No, break-before-make functionality is exclusive to the DG413LE variant, which contains two normally open and two normally closed switches.
