DG441LDY-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG441LDY-T1-E3 is a precision monolithic quad single-pole single-throw (SPST) low-voltage CMOS analog switch manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 2.7 V to 12 V or dual supplies of ±3 V to ±6 V. The device features a typical drain-source on-resistance of 17 Ω and fast switching times with a turn-on time of 20 ns and turn-off time of 12 ns. It offers low leakage current of 0.25 nA, 2000 V ESD protection, and TTL/CMOS compatibility. The component is housed in a 16-pin narrow SOIC package and supports an operating temperature range from -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix T1 indicates tape and reel packaging when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the narrow SOIC-16 footprint matches the design layout requirements. Check for any updated environmental declarations or material change notices before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low voltage operation and high-speed signal switching. Compare on-resistance flatness and charge injection specifications against system requirements. Consider the 16-pin narrow SOIC package constraints during PCB layout. Evaluate thermal dissipation capabilities based on the expected load current and ambient temperature conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG441L/DG442L series of low-voltage CMOS analog switches. It serves as a companion device to industry-standard parts with improved performance characteristics. The DG441L variant provides four independent SPST switches, while the DG442L offers complementary control logic. Both share similar electrical specifications and pin configurations.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic control behavior of the DG441L?

The DG441L responds to opposite control logic where a Logic '0' turns the switch ON and a Logic '1' turns it OFF.

What is the maximum analog signal range for the DG441L?

The analog signal range extends from V- to V+, allowing full rail-to-rail operation within the specified supply voltage limits.

How does the DG441L handle signals exceeding supply rails?

Signals on Sx, Dx, or INx exceeding V+ or V- will be clamped by internal diodes. Forward diode current must be limited to maximum ratings.
