Overview
The DG409LEDN-T1-GE4 is a dual 4-channel differential analog multiplexer from the DG409LE series, manufactured by Vishay Siliconix. It operates on single supplies of 3 V to 16 V or dual supplies of ±3 V to ±8 V. The device features a typical on-resistance of 17 Ω and low power consumption of 6 μA maximum. It includes an enable function for stacking devices and guarantees break-before-make switching. The component is housed in a 16-pin QFN (3 mm x 3 mm) package with tape and reel packaging.
Feature Summary
- Dual 4-channel differential configuration connecting four differential inputs to a common dual output via binary addressing.
- Internal logic regulator reduces power consumption, making it suitable for battery-operated applications.
- Guaranteed break-before-make switching action prevents momentary crosstalk between adjacent channels.
- TTL, CMOS, and LV logic compatible control inputs simplify interface design.
Applications
- Automatic test equipment
- Data acquisition systems
- Medical and healthcare systems
- Battery powered systems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and compliance status. Confirm availability through authorized distributors as manufacturing locations may vary. Ensure the component meets the required environmental specifications for the intended application environment before finalizing procurement.
Selection Notes
Select this part when a differential signal path is required within a compact surface-mount footprint. The DG409LE offers lower on-resistance compared to standard DG409 variants. Verify that the system voltage range falls within the specified 3 V to 16 V single supply or ±3 V to ±8 V dual supply limits for optimal performance.
Part Context
This component belongs to the DG409LE family, which provides enhanced performance over the legacy DG409 series. It shares pin-for-pin compatibility with the DG408LE and DG509 series, facilitating direct upgrades in existing designs requiring improved speed and lower resistance characteristics.
Replacement Considerations
DG409LE variants in different packages such as TSSOP-16 or SOIC-16 offer functional equivalence. Standard DG409 parts are pin-compatible but lack the low-power internal regulator. Verify thermal dissipation requirements when substituting into the QFN-16 form factor.
