Overview
The DG441LDQ-T1-E3 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 a typical on-resistance of 17 Ω and fast switching times with a maximum turn-on time of 60 ns and turn-off time of 35 ns at room temperature under standard test conditions. It offers low leakage current, high off-isolation, and minimal crosstalk. The component is housed in a 16-lead Thin Shrink Small Outline Package (TSSOP) and supports an operating temperature range from -40 °C to +85 °C.
Feature Summary
- BiCMOS wafer fabrication technology enables operation across wide dynamic ranges with low signal errors and distortion.
- Features break-before-make switching action to prevent signal shorting during channel transitions.
- Compatible with TTL and CMOS logic levels for simple digital interfacing.
Applications
- Precision automatic test equipment
- Precision data acquisition systems
- Audio and video signal routing
- Communication systems including DSL and DSLAM
Procurement Notes
Verify the specific suffix 'T1' corresponds to tape-and-reel packaging when sourcing. Confirm RoHS compliance status as required by project specifications. Ensure the ordering part number matches the exact package type and temperature grade needed for the design.
Selection Notes
Select this component for applications requiring low voltage operation and fast switching speeds. Verify that the supply voltage range meets the system requirements. Check the on-resistance match between channels if signal integrity is critical. Ensure the TSSOP package footprint aligns with the PCB layout constraints.
Part Context
This part belongs to the DG441L/DG442L family of low-voltage CMOS analog switches. It serves as a companion to industry-standard devices but offers improved performance characteristics. The DG441L variant provides normally open switches, while the DG442L provides normally closed switches.
Replacement Considerations
Check for direct pin-compatible alternatives within the same product family. Verify that any substitute maintains the required switching speed and on-resistance specifications. Ensure the replacement package matches the existing board footprint.
