DESCRIPTION

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.

Built on the Vishay 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.

The DG271B has a redesign internal regulator which

improves start-up over the DG271.

As a committed partner to the community and the

environment, Vishay Siliconix manufactures this product

with the lead (Pb)-free device terminations. For analog

switching products manufactured with 100 matte tin

device terminations, the lead (Pb)-free “-E3” suffix is being

used as a designator.
