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鈥?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 鈥溾€擡3鈥?suffix is being used as
a designator.
