| DG2020 New Product Vishay Siliconix Low-Voltage Single Asymmetrical SPDT Analog Switch FEATURES D Low Voltage Operation (2.7 V to 5.5 V) D Low On-Resistance - rON - NO = 0.8 W - NC = 1.2 W D Low Power Consumption D TTL/CMOS Compatible D TSOP-6 Package BENEFITS D D D D Reduced Power Consumption Simple Logic Interface High Accuracy Reduce Board Space APPLICATIONS D D D D Cellular Phones Communication Systems Portable Test Equipment Battery Operated Systems DESCRIPTION The DG2020 is a single-pole/double-throw monolithic CMOS analog switch designed for high performance switching of analog signals. Combining low power, high speed, low on-resistance and small physical size, the DG2020 is ideal for portable and battery powered applications requiring high performance and efficient use of board space. The DG2020 is built on Vishay Siliconix's low voltage JI2 process. An epitaxial layer prevents latchup. Break-before-make is guaranteed. The switch conducts equally well in both directions when on, and blocks up to the power supply level when off.
