The DG2520/DG2521 are low-voltage single single-pole/double-throw monolithic CMOS analog switches. Designedto operate from 1.8 V to 5.5 V power supply, the DG2520/DG2521 provide low on-resistance (0.8 Ω), excellent onresistancematching (0.06 Ω) and flatness (0.2 Ω) over theenTIre signal range.The DG2520/DG2521 offers the advantage of high linearitythat reduces signal distorTIon, making ideal for audio, video,and USB signal rouTIng applicaTIons. Additionally, theDG2520/DG2521 are 1.6 V logic compatible within the fulloperation voltage range.The DG2520/DG2521 offer over current protection. The protectioncircuitry activates when voltage drop across switchreaches 0.6 V typical. A direct/sustained short circuit willcause the switch to pulse on for typically less than 1 μs, thenturn off. The switch turns on after 5 ms. If the short circuitcondition remains, the switch turns off and on to producea pulsed output. The current limiting circuitry is notinstantaneous, and therefore will not activate when the outputcharges a small 0.1 μF capacitor.Built on Vishay Siliconix’s proprietary sub-micron high-densityprocess, the DG2520/DG2521 brings low power consumptionat the same time as reduces PCB spacing with theTSOP6 packageAs a committed partner to the community and the environment,Vishay Siliconix manufactures this product with thelead (Pb)-free device terminations. For analog switchingproducts manufactured with 100 % matte tin device termination,the lead (Pb)-free “- E3” suffix is being used as a designator.FUNCTIONAL BLOCK DIAGRAM AND PINCONFIGURATION
