DESCRIPTION
The DG2711 is a sub-ohm single-pole/double-throw monolithic CMOS analog switch designed for high performance switching of analog signals. Combining low power, high speed (tON: 25 ns, tOFF: 14 ns), low on-resistance (rDS(on): 0.44 W) and small physical size (SC70), the DG2711 is ideal for portable and battery powered applications requiring high performance and efficient use of board space. The DG2711 is built on Vishay Siliconix's low voltage submicron CMOS process. An epitaxial layer prevents latchup. Break-before-make is guaranteed for DG2711. Each switch conducts equally well in both directions when on, and blocks up to the power supply level when off.
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 terminations, the lead (Pb)-free "--E3" suffix is being used as a designator.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
