DESCRIPTION
The DG2020 is a single-pole/double-throw monolithic CMOS
analog switch designed for high performance switching of
analog signals. Combining low power, high speed, low
on-resistance and small physical size, the DG2020 is ideal for
portable and battery powered applications requiring high
performance and efficient use of board space.
The DG2020 is built on Vishay Siliconix's low voltage JI2 process.
An epitaxial layer prevents latchup. Break-before-make is
guaranteed.
The switch conducts equally well in both directions when on,
and blocks up to the power supply level when off.
