Overview
The Vishay Siliconix DG412LDQ is a precision monolithic quad single-pole single-throw (SPST) low-voltage CMOS analog switch housed in a 16-pin Thin-Shrink Small Outline Package (TSSOP). 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 provides 2000 V ESD protection.
Feature Summary
- Low voltage operation compatible with single and dual power supplies
- Fast switching speeds with minimal insertion loss
- Break-before-make switching action for signal integrity
- High off-isolation and low crosstalk performance
Applications
- Precision automatic test equipment
- Audio and video signal routing
- DSL and DSLAM systems
- Battery powered systems
Procurement Notes
Verify the specific suffix 'LDQ' confirms the TSSOP-16 package and commercial temperature range (-40 °C to +85 °C). Confirm RoHS compliance status if required by procurement specifications. Ensure design compatibility with the specified supply voltage ranges before ordering.
Selection Notes
Select the DG412LDQ when opposite control logic is required compared to the DG411L series. Verify that the 17 Ω on-resistance meets system requirements at the intended operating voltage. Ensure the TSSOP-16 footprint matches the PCB layout constraints.
Part Context
The DG412LDQ belongs to the DG411L/DG412L/DG413L family of low-voltage analog switches. These devices are pin-for-pin compatible with the industry-standard DG411/412/413 but offer improved performance characteristics suitable for modern low-voltage applications.

FAQ
What is the logic sense of the DG412LDQ?
The DG412LDQ responds to opposite control logic compared to the DG411L. When the input is Logic 0, the switches are ON; when the input is Logic 1, the switches are OFF.
What is the maximum analog signal range?
The analog signal range spans the full supply voltage, from 0 V to 12 V for single supply operation, or -5 V to +5 V for dual ±5 V supply operation.
Does the DG412LDQ support break-before-make switching?
No, break-before-make switching is a feature specific to the DG413L variant within this family. The DG412LDQ follows standard SPST switching behavior based on its logic inputs.
