Overview
The DG409LDQ-T1-E3 is a dual 4-channel differential analog multiplexer manufactured by Vishay Siliconix. It operates on single supplies from 2.7 V to 12 V or dual supplies of ±3 V to ±6 V. The device features a typical on-resistance of 17 Ω, enable turn-on time of 38 ns, and turn-off time of 18 ns. Leakage current is limited to 0.2 nA maximum with 1 pC charge injection. It utilizes BiCMOS technology for low power consumption and high off-isolation of 82 dB at 1 MHz. The component is housed in a 16-pin TSSOP package and supports an operating temperature range of -40 °C to +85 °C.
Feature Summary
- Pin-for-pin compatibility with standard DG408 and DG409 devices
- Guaranteed break-before-make switching action to prevent crosstalk
- Low charge injection of 1 pC for high signal integrity
- TTL, CMOS, and LV logic compatible
Applications
- Data acquisition systems
- Battery operated equipment
- Portable test equipment
- Sample and hold circuits
- Communication systems
Procurement Notes
Verify the specific suffix 'T1' indicates tape and reel packaging when sourcing this part number. Confirm RoHS compliance status as indicated by the '-E3' designation. Ensure the TSSOP-16 package dimensions match the target PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select the DG409LDQ variant specifically for applications requiring dual differential channel routing rather than single-ended multiplexing. Verify that the supply voltage range aligns with the 2.7 V to 12 V single or ±3 V to ±6 V dual supply specifications. Consider the 17 Ω typical on-resistance for signal path loss calculations.
Part Context
This component belongs to the DG408L/DG409L series, which are low-voltage companion devices to the industry-standard DG408/DG409. The L-series offers improved performance metrics including lower on-resistance, faster switching times, and reduced leakage compared to the original generation.
