DESCRIPTION
The DG2718 is a dual double-pole/double-throw monolithic
CMOS analog switch designed for high performance switching
of analog signals. Combining low power, high speed, low
on-resistance and small physical size, the DG2718 is ideal for
portable and battery powered applications requiring high
performance and efficient use of board space.
The DG2718 is built on Vishay Siliconix’s low voltage process. An
epitaxial layer prevents latchup. Break-before-make is
guaranteed.
The switch conducts equally well in both directions when on,
and blocks up to the power supply level when off.

Notes:
a. Signals on NC, NO, or COM or IN exceeding V+ will be clamped by inter-
nal diodes. Limit forward diode current to maximum current ratings.
b. All leads welded or soldered to PC Board.
c. Derate 17.3 mW/_C above 70_C
d. Manual soldering with iron is not recommended for leadless components.
The QFN is a leadless package. The end of the lead terminal is exposed
copper (not plated) as a result of the singulation process in manufactur-
ing. A solder fillet at the exposed copper lip cannot be guaranteed and is
not required to ensure adequate bottom side solder interconnection.

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.
