Overview
The DG409LEDQ-GE3 is a dual 4-channel differential analog multiplexer from the Vishay Siliconix DG409LE series, housed in a 16-pin TSSOP package. It operates on single supplies of 3 V to 16 V or dual supplies of ±3 V to ±8 V. Key electrical parameters include a maximum on-resistance of 27 Ω, an enable turn-on time of 82 ns, and an enable turn-off time of 50 ns. The device features a maximum power dissipation of 600 mW, a supply current of 6 μA, and operates within a temperature range of -40 °C to +85 °C.
Feature Summary
- Dual 4-channel differential configuration with binary address control
- Internal logic regulator for low power consumption
- Guaranteed break-before-make switching action
- TTL, CMOS, and LV logic compatibility
Applications
- Automatic test equipment
- Data acquisition systems
- Medical and healthcare systems
- Battery powered systems
Procurement Notes
Verify the specific suffix 'Q' confirms the TSSOP-16 package type and 'GE3' indicates lead-free RoHS compliance. Confirm the manufacturer datasheet revision matches the required specifications. Ensure the ordering information aligns with the intended tube packaging quantity of 360 units.
Selection Notes
Select this component when a differential signal path is required within a dual-supply or single-supply environment. The internal regulator simplifies logic interface design. Verify that the 27 Ω on-resistance meets the system's voltage drop requirements at the target load current.
Part Context
This part belongs to the DG409LE family, which offers pin-for-pin compatibility with legacy DG409 and DG509 devices. The LE designation signifies enhanced performance characteristics including lower on-resistance and faster switching speeds compared to standard variants.
Replacement Considerations
DG409LEDY-GE3 (SOIC-16 package) and DG409LEDQ-T1-GE3 (Tape and Reel packaging).
FAQ
What is the function of the Enable (EN) pin?
The EN pin allows the user to reset all switches to the off state, facilitating the stacking of several devices.
How does the device handle channel transitions?
It utilizes a guaranteed break-before-make switching action to prevent momentary crosstalk between adjacent channels during transitions.
Is the device compatible with 3 V logic levels?
Yes, the control inputs are TTL, CMOS, and LV logic compatible down to 3 V operation.
