| DG2517/DG2518 Vishay Siliconix 3 , High Bandwidth, Dual SPDT Analog Switch DESCRIPTION The DG2517/DG2518 are low-voltage dual single-pole/double-throw monolithic CMOS analog switches. Designed to operate from 1.8 V to 5.5 V power supply, the DG2517/ DG2518 achieves a bandwidth of 157 MHz while providing low on-resistance (3 ), excellent on-resistance matching (0.2 ) and flatness (1 ) over the entire signal range. The DG2517/DG2518 offers the advantage of high linearity that reduces signal distortion, making ideal for audio, video, and USB signal routing applications. Additionally, the DG2517/DG2518 are 1.6 V logic compatible within the full operation voltage range. Built on Vishay Siliconix's proprietary sub-micron high-density process, the DG2517/DG2518 brings low power consumption at the same time as reduces PCB spacing with the MSOP10 and DFN10 packages. As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with the lead (Pb)-free device terminations. The DFN package has a nickel-palladium-gold device termination and is represented by the lead (Pb)-free "-E4" suffix. The MSOP package uses 100 % matte Tin device termination and is represented by the lead (Pb)- free "-E3" suffix. Both the matte Tin and nickelpalladium-gold device terminations meet all JEDEC standards for reflow and MSL ratings.
