DG2714 New Product Vishay Siliconix Low-Voltage Single SPDT Analog Switch FEATURES BENEFITS APPLICATIONS D D D D D D D D D D D D D D D Low Voltage Operation (1.6 V to 3.6 V) Low On-Resistance - rDS(on): 0.85 W Typ. Fast Switching - tON : 28 ns, tOFF: 12 ns Low Leakage TTL/CMOS Compatible 6-Pin SC-70 Package Reduced Power Consumption Simple Logic Interface High Accuracy Reduce Board Space Cellular Phones Communication Systems Portable Test Equipment Battery Operated Systems Sample and Hold Circuits DESCRIPTION The DG2714 is a single-pole/double-throw monolithic CMOS analog switch designed for high performance switching of analog signals. Combining low power, high speed (tON: 28 ns, tOFF: 12 ns), low on-resistance (rDS(on): 0.85 W) and small physical size (SC70), the DG2714 is ideal for portable and battery powered applications requiring high performance and efficient use of board space. The DG2714 is built on Vishay Siliconix’s low voltage submicron CMOS process. An epitaxial layer prevents latchup. Break-before -make is guaranteed for DG2714. Each switch conducts equally well in both directions when on, and blocks up to the power supply level when off.
