Overview
The DG409LEDY-GE3 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 maximum on-resistance of 27 Ω at room temperature and up to 30 Ω across the full -40 °C to +85 °C range. Switching times include a maximum enable turn-on time of 72 ns and turn-off time of 47 ns at 12 V supply. Leakage current is limited to 1 nA maximum. It utilizes a 16-pin SOIC package.
Feature Summary
- Dual 4-channel differential configuration for connecting four differential inputs to common outputs
- Internal logic regulator reduces power consumption for battery-operated applications
- TTL, CMOS, and LV logic compatible control inputs with guaranteed break-before-make switching
- Low leakage and low parasitic capacitances for high accuracy signal routing
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 against the manufacturer's official documentation to confirm package type and compliance status. The 'Y' suffix indicates a narrow SOIC-16 package, while 'GE3' denotes lead-free and RoHS compliance. Confirm that the required quantity matches the standard tube packaging of 500 units specified in the ordering information section of the datasheet.
Selection Notes
Select this component when a dual differential multiplexer is required within a 3 V to 16 V single supply or ±3 V to ±8 V dual supply range. Ensure the application demands low on-resistance and fast switching speeds compatible with TTL or CMOS logic levels. Verify that the 16-pin SOIC footprint fits the PCB layout constraints and that the thermal dissipation requirements are met within the operating temperature range.
Part Context
This part belongs to the DG409LE family of high-performance analog multiplexers. It shares pin-for-pin compatibility with the legacy DG409 and DG509 devices. The LE series distinguishes itself through lower on-resistance and reduced power consumption compared to earlier generations, making it suitable for modern low-power instrumentation and portable electronic designs.
Replacement Considerations
The DG409DY-T1-E3 serves as a tape-and-reel alternative within the same package family. For legacy replacements, the DG409DJ-E3 offers a PDIP-16 through-hole option, though it operates at higher voltage ranges. Direct pin-compatible substitutes include the DG509 series.
