DG2019DN-T1-E4

Analog Switches, Multiplexers, Demultiplexers Overview

The Vishay Siliconix DG2019DN-T1-E4 is a low voltage, single supply analog switch featuring four independent SPDT channels in a QFN-16 package. It operates on a 1.8 V to 5.5 V supply and provides an on-resistance of 6 Ω at 2.7 V. The device supports a bandwidth exceeding 180 MHz with turn-on and turn-off times of 42 ns and 16 ns respectively. It utilizes a VL pin for 1.0 V logic threshold compatibility and includes brake-before-make functionality.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix T1-E4 against the manufacturer's current ordering information to confirm packaging type and RoHS compliance status. Confirm availability through authorized distributors as production lifecycles may change. Validate that the QFN-16 package dimensions match the design footprint requirements before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single control line must manage multiple independent signal paths. The DG2019 differs from the DG2018 by using one control pin for all four switches rather than two pins for dual DPDT pairs. Ensure the application requires single-supply operation within the 1.8 V to 5.5 V range and benefits from the low 1.0 V logic threshold provided by the VL pin.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2018/DG2019 family of low voltage analog switches manufactured by Vishay Siliconix. Both devices share identical electrical characteristics but differ in control architecture. The DG2019 specifically offers quad SPDT configuration controlled by a single input, whereas the DG2018 provides dual DPDT configuration with two inputs.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the DG2019 control logic differ from the DG2018?

The DG2019 uses a single control pin (IN) to operate all four independent SPDT switches. In contrast, the DG2018 uses two control pins (IN1, IN2) to operate two dual DPDT switches.

What is the function of the VL pin on the DG2019?

The VL pin allows the device to accept a 1.0 V threshold for the control pin when powered with 1.5 V, ensuring compatibility with low voltage digital logic.

Does the DG2019 support break-before-make switching?

Yes, brake-before-make is guaranteed for all SPDT switches in the DG2019 to prevent short circuits during switching transitions.
