DG2714 Datasheet

DG2714
Vishay Siliconix
Low-Voltage Single SPDT Analog Switch
DESCRIPTION
FEATURES
The DG2714 is a single-pole/double-throw monolithic CMOS
analog switch designed for high performance switching of
analog signals. Combining low power, high speed
(tON: 28 ns, tOFF: 12 ns), low on-resistance (rDS(on): 0.85 Ω)
and small physical size (SC70), the DG2714 is ideal for
portable and battery powered applications requiring high
performance and efficient use of board space.
•
•
•
•
•
•
The DG2714 is built on Vishay Siliconix’s low voltage
submicron CMOS process. An epitaxial layer prevents
latchup. Break-before -make is guaranteed for DG2714.
BENEFITS
Each switch conducts equally well in both directions when
on, and blocks up to the power supply level when off.

Notes:
a. Room = 25 °C, Full = as determined by the operating suffix.
b. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
c. Typical values are for design aid only, not guaranteed nor subject to production testing.
d. Guarantee by design, nor subjected to production test.
e. VIN = input voltage to perform proper function.
f. Guaranteed by 3 V leakage testing, not production tested.
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.
