DG2535/DG2536
Vishay Siliconix
0.35-Ω Low-Voltage Dual SPDT Analog Switch
DESCRIPTION
FEATURES
The DG2535/DG2536 is a sub 1 Ω (0.35 Ω at 2.7 V) dual
SPDT analog switches designed for low voltage applications.
The DG2535/DG2536 has on-resistance matching (less than
0.05 Ω at 2.7 V) and flatness (less than 0.2 Ω at 2.7 V) that are
guaranteed over the entire voltage range. Additionally, low
logic thresholds make the DG2535/DG2536 an ideal interface
to low voltage DSP control signals.
The DG2535/DG2536 has fast switching speed with
break-before-make guaranteed. In the On condition, all
switching elements conduct equally in both directions.
Off-isolation and crosstalk is - 69 dB at 100 kHz.
The DG2535/DG2536 is built on Vishay Siliconix’s
high-density low voltage CMOS process. An eptiaxial layer is
built in to prevent latchup. The DG2535/DG2536 contains the
additional benefit of 2,000 V ESD protection.
In space saving MSOP-10 and DFN-10 lead (Pb)-free
packages, the DG2535/DG2536 are high performance, low
rON switches for battery powered applications. No lead (Pb) is
used in the manufacturing process either inside the device/
package or on the external terminations. 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 in DFN packages, the lead (Pb)-free "-E3/E4"
suffix is being used as a designator. Lead (Pb)-free DFN
products purchased at any time will have either a
nickel-palladium-gold device termination or a 100 % matte tin
device termination. The different lead (Pb)-free materials are
interchangeable and meet all JEDEC standards for reflow and
MSL rating.

Notes:
a. Signals on NC, NO, or COM or IN exceeding 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 4.0 mW/°C above 70 °C
d. Derate 14.9 mW/°C above 70 °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.
