Combining low power, high speed (tON: 25 ns, tOFF: 20 ns), the DG9432/9433/9434 is ideal for portable and battery powered applications requiring high performance and efficient use of board space. The DG9432/9433/9434 is built on Vishay Siliconix’s low voltage BCD-15 process. An epitaxial layer prevents latchup. Break-before -make is guaranteed for DG9432/9433/9434. Each switch conducts equally well in both directions when on, and blocks up to the power supply level when off.
