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.

Notes:
a. Signals on SX, DX, or INX exceeding V+ or V− will be clamped by internal
diodes. Limit forward diode current to maximum current ratings.
b. All leads welded or soldered to PC Board.
c. Derate 6.5 mW/_C above 75_C
d. Derate 7.6 mW/_C above 75_C
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
