DG9432, DG9433, DG9434 Vishay Siliconix Low-Voltage Dual SPST Analog Switch DESCRIPTION The DG9432, DG9433, DG9434 is a dual single-pole/singlethrow monolithic CMOS analog switch designed for high performance switching of analog signals. Combining low power, high speed (tON: 25 ns, tOFF: 20 ns), the DG9432, DG9433, DG9434 is ideal for portable and battery powered applications requiring high performance and efficient use of board space. The DG9432, DG9433, DG9434 is built on Vishay Siliconix’s low voltage BCD-15 process. An epitaxial layer prevents latchup. Break-before-make is guaranteed for DG9432, DG9433, DG9434. Each switch conducts equally well in both directions when on, and blocks up to the power supply level when off.
