DG9426EDQ-T1-GE3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG9426EDQ-T1-GE3 is a monolithic quad single-pole-single-throw analog switch manufactured by Vishay Siliconix. It features two normally open and two normally closed switches, enabling configurations of four SPST, two SPDT, or one DPDT. The device operates on single supplies from 3 V to 16 V or dual supplies from ±3 V to ±8 V. Key electrical parameters include a typical on-resistance of 1.6 Ω (maximum 4 Ω at room temperature), turn-on time of 51 ns, and charge injection of 38 pC. It supports bidirectional rail-to-rail signal switching with low leakage current and is housed in a 16-lead TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package type and tape-and-reel quantity. Confirm that the component meets RoHS standards and check the active status code before procurement. Ensure the supply voltage requirements align with the application's operational range.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when mixed normally open and normally closed contacts are required within a single package. Verify that the maximum on-resistance and charge injection values meet the signal integrity requirements. Ensure the operating temperature range covers the intended environmental conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG9424E/DG9425E/DG9426E family of quad SPST analog switches. While DG9424E and DG9425E differ only in logic level response, the DG9426E uniquely combines both normally open and normally closed switches. All variants share similar electrical characteristics and packaging options.
