DG9431DY

DG9431 Vishay Siliconix Low-Voltage Single SPDT Analog Switch DESCRIPTION FEATURES The DG9431 is a single-pole/double-throw monolithic CMOS analog device designed for high performance switching of analog signals. Combining low power, high speed (tON: 35 ns, tOFF: 20 ns), low on-resistance (rDS(on): 20 Ω) and small physical size (TSOP-6), the DG9431 is ideal for portable and battery powered applications requiring high performance and efficient use of board space. • • • • • • • • • • The DG9431 is built on Vishay Siliconix’s low voltage BCD-15 process. Minimum ESD protection, per Method 3015.7, is 2000 V. An epitaxial layer prevents latchup. Break-before -make is guaranteed for DG9431. 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.
