DG1411EN-T1-GE4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG1411EN-T1-GE4 is a precision monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It features an on-resistance of 1.5 Ω typical and operates from single supplies of 4.5 V to 24 V or dual supplies of ±4.5 V to ±16.5 V. The device provides rail-to-rail signal handling, low charge injection, and fast switching times with a turn-on time of 100 ns typical. Packaged in a QFN-16 (4 mm x 4 mm) format, it supports an operating temperature range from -40 °C to +125 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the package type matches the design requirements, as this specific part number denotes the QFN-16 variant. Confirm that the normally closed logic state aligns with the system's default switch position needs. Ensure the supply voltage range accommodates the intended operational environment within the specified limits.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST switch with normally closed behavior is required. Consider the DG1412EN-T1-GE4 if normally open logic is preferred instead. Evaluate the on-resistance flatness and leakage current specifications against the signal integrity requirements of the application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the DG141x family of precision analog switches, which includes the DG1412 and DG1413 variants. These components share similar electrical characteristics but differ in their internal switch logic states. The family is designed for high-performance signal routing in compact surface-mount packages.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the default state of the switches for the DG1411?

The DG1411 features four independently selectable SPST switches that are normally closed.

Does the DG1411 require a separate logic supply voltage?

No, the device does not require a VL logic supply; digital inputs have thresholds compatible with low-voltage TTL/CMOS.

What is the maximum supply voltage rating?

The absolute maximum rating allows for a maximum supply voltage difference of 35 V between V+ and V-.
