Combining low power (0.35 mW) with high speed (tON: 68 ns), the DG411HS family is ideally suited for portable and battery powered industrial and military applications. To achieve high-voltage ratings and superior switching performance, the DG411HS series was built on Vishay Siliconix's high voltage silicon gate process. An epitaxial layer prevents latchup. Each switch conducts equally well in both directions when on, and blocks input voltages up to the supply levels when off. The DG411HS and DG412HS respond to opposite control logic as shown in the Truth Table. The DG413HS has two normally open and two normally closed switches. V+ to V-. 44 V GND to V-. 25 V VL.
