The DG271B 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.
switch conducts equally well in both directions when on, and
blocks up to the supply voltage when off. An epitaxial layer
prevents latchup.
Built on the Vishay Siliconix’ proprietary high voltage silicon
gate process to achieve superior on/off performance, each
The DG271B has a redesign internal regulator which improves
start-up over the DG271.
