DG2717 Datasheet

DG2717
Vishay Siliconix
Low-Voltage, 0.45-Ω, SPDT Analog Switch
DESCRIPTION
FEATURES
The DG2717 is a low voltage, low on resistance, single- pole/
double-throw (SPDT) monolithic CMOS analog switch
designed for high performance switching of analog signals.
Combining low-power, high speed, low on-resistance, and
small package size, the DG2717 is ideal for portable and
battery power applications.

•
•
•
The DG2717 has an operation range from 1.6 V to 4.3 V
single supply, and is low voltage logic compatible within this
range, allowing the easy interface with low voltage DSP or
MCU control logic. These traits make it ideal for one cell
Li-ion battery direct power.
The switch conducts signals within power rails equally well in
both directions when on, and blocks up to the power supply
level when off. Break-before-make is guaranteed.
The DG2717 is built on Vishay Siliconix’s sub micron CMOS
low voltage process.
As a committed partner to the community and the
environment, Vishay Siliconix manufactures this product
with lead (Pb)-free device terminations. For analog switching
products manufactured in SC89 package, the lead (Pb)-free
"E3" suffix is being used as a designator. It has a Tin device
termination that meets all JEDEC standards for reflow and
MSL rating.

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.
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.
