DEs criptIONThe DG9411 is a single-pole/double-throw monolithic CMOSanalog switch designed for high performance switching ofanalog signals. Combining low power, high speed (tON: 9 ns,tOFF: 5 ns), low on-resistance (rDS(on): 7 Ω) and smallphysical size (SC70), the DG9411 is ideal for portable andbattery powered applications requiring high performanceand efficient use of board space.The DG9411 is built on Vishay Siliconix’s low voltage JI2process. An epitaxial layer prevents latchup. Break-before -make is guaranteed for DG9411.Each switch conducts equally well in both directions whenon, and blocks up to the power supply level when off.
