The DG271 high speed quad single-pole single-throw
analog switch is intended for applications that require low
on-resistance, low leakage currents, and fast switching
speeds.
Built on Siliconix’ proprietary high voltage silicon gate
process to achieve superior on/off performance, each
switch conducts equally well in both directions when on,
and blocks up to the supply voltage when off. An epitaxial
layer prevents latchup.
