DG2518DN-T1-E4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2518DN-T1-E4 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 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 25 ns and 20 ns respectively under specified conditions. It utilizes a DFN-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 current manufacturer documentation to confirm lead-free termination compliance and package type. Confirm that the DFN-10 package variant matches the required PCB footprint and thermal dissipation specifications for the target application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual-channel SPDT switch is required within a 1.8 V to 5.5 V supply range. Ensure the design accommodates the 4 Ω maximum on-resistance and 242 MHz bandwidth limits. Verify that the 1.6 V logic compatibility aligns with the system's control voltage levels.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2517/DG2518 family of low-voltage analog switches. The DG2518 specifically denotes the dual SPDT configuration housed in a DFN-10 package with E4 lead-free terminations. It shares functional similarities with the DG2517 but differs in pinout arrangement for the normally closed contacts.
