DG2517DQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The Vishay Siliconix DG2517DQ-T1-E3 is a dual single-pole/double-throw (SPDT) analog switch housed in a 10-lead MSOP package. It operates on a single supply voltage ranging from 1.8 V to 5.5 V. Key electrical specifications include an on-resistance of 3 Ω at 4.2 V, a -3 dB bandwidth of 242 MHz, and off-isolation of -51 dB at 10 MHz. The device features low power consumption with a supply current of 1 µA maximum and supports 1.6 V logic compatibility. It provides full rail signal swing and excellent linearity for audio, video, and USB applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix '-E3' confirms the use of 100% matte tin terminations, which are lead-free and compliant with JEDEC reflow standards. Ensure the 'DQ' designation matches the required MSOP-10 package type. Confirm the temperature range specification aligns with the intended operational environment requirements before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual-channel analog switch is required for low-voltage systems operating between 1.8 V and 5.5 V. The 3 Ω on-resistance and 242 MHz bandwidth make it suitable for high-frequency signal routing. Consider the MSOP-10 package for space-constrained PCB layouts requiring small footprint solutions while maintaining thermal performance within specified derating limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2517/DG2518 family of low-voltage CMOS analog switches manufactured by Vishay Siliconix. The DG2517 variant specifically routes COM1 to NO1 or NC1 based on input logic. It utilizes a proprietary sub-micron high-density process to achieve low power consumption and reduced PCB spacing compared to older technologies.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG2518DQ-T1-E3 is the complementary part in the same series but with different internal pinout configurations for the second channel. Verify pin compatibility if substituting directly, as the functional block diagram differs between the DG2517 and DG2518 models despite identical electrical specifications.
