DG2518DQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2518DQ-T1-E3 is a dual single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 1.8 V to 5.5 V and features a maximum on-resistance of 4.5 Ω at 2.7 V and 4.3 Ω at 4.2 V. The device provides a -3 dB bandwidth of 242 MHz, with turn-on and turn-off times reaching up to 50 ns and 35 ns respectively under specified conditions. It utilizes an MSOP-10 package and supports logic levels compatible with inputs as low as 1.6 V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and termination material. The '-E3' suffix indicates a lead-free matte tin termination in an MSOP package. Ensure that the component meets all relevant environmental compliance standards required for your specific manufacturing process before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual SPDT configuration is required within a compact surface-mount footprint. Consider the 1.8 V to 5.5 V supply range and the 1.6 V logic compatibility for systems utilizing lower voltage control signals. Evaluate the 4.5 Ω on-resistance limit to ensure it aligns with the signal integrity requirements of the target application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2517/DG2518 family of low-voltage CMOS analog switches. The DG2518 variant specifically offers a dual SPDT configuration housed in an MSOP-10 package. It shares core electrical characteristics with the DG2517 but differs in internal pin mapping and functional block arrangement.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG2517DQ-T1-E3 serves as a direct functional alternative within the same series, offering identical electrical specifications in the same MSOP-10 package. Verify pinout compatibility during substitution due to potential differences in internal channel mapping between the two variants.
