The DG2788/DG2789 are monolithic CMOS analog switching products designed for high performance switching of analog signals. Combining low power, high speed, low onresistance and small physical size, the DG2788/DG2789 are ideal for portable and battery powered applications requiring high performance and efficient use of board space. The DG2788/DG2789 are built on Vishay Siliconix's low voltage process. An epitaxial layer prevents latchup. Breakbefore-make is guaranteed. The switch conducts equally well in both directions when on, and blocks up to the power supply level when off. The DG2788 is configured as a dual Double Pole Double Throw switches while the DG2789 is configured as a Quad Single Pole Double Throw. The DG2789 has one control pin for all four SPDT switches and also has an enable pin that can turn all switches off.
