| DG2520/DG2521 New Product Vishay Siliconix Sub-, Low Voltage, SPDT Analog Switches with Over Current Protection DESCRIPTION The DG2520/DG2521 are low-voltage single single-pole/ double-throw monolithic CMOS analog switches. Designed to operate from 1.8 V to 5.5 V power supply, the DG2520/ DG2521 provide low on-resistance (0.8 ), excellent onresistance matching (0.06 ) and flatness (0.2 ) over the entire signal range. The DG2520/DG2521 offers the advantage of high linearity that reduces signal distortion, making ideal for audio, video, and USB signal routing applications. Additionally, the DG2520/DG2521 are 1.6 V logic compatible within the full operation voltage range. The DG2520/DG2521 offer over current protection. The protection circuitry activates when voltage drop across switch reaches 0.6 V typical. A direct/sustained short circuit will cause the switch to pulse on for typically less than 1 s, then turn off. The switch turns on after 5 ms. If the short circuit condition remains, the switch turns off and on to produce a pulsed output. The current limiting circuitry is not instantaneous, and therefore will not activate when the output charges a small 0.1 F capacitor. Built on Vishay Siliconix's proprietary sub-micron high-density process, the DG2520/DG2521 brings low power consumption at the same time as reduces PCB spacing with the TSOP6 package As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with the lead (Pb)-free device terminations. For analog switching products manufactured with 100 % matte tin device termination, the lead (Pb)-free "- E3" suffix is being used as a designator.
