DG2520/DG2521
Vishay Siliconix
New Product
Sub-Ω, Low Voltage, SPDT Analog Switches
with Over Current Protection
DESCRIPTION
FEATURES
The DG2520/DG2521 are low-voltage single single-pole/
double-throw monolithic CMOS analog switches. Designed
to operate from 1.8 V to 5.5 V power supply, the DG2520/
DG2521 provide low on-resistance (0.8 Ω), excellent onresistance matching (0.06 Ω) and flatness (0.2 Ω) over the
entire signal range.

The DG2520/DG2521 offers the advantage of high linearity
that reduces signal distortion, making ideal for audio, video,
and USB signal routing applications. Additionally, the
DG2520/DG2521 are 1.6 V logic compatible within the full
operation voltage range.
The DG2520/DG2521 offer over current protection. The protection circuitry activates when voltage drop across switch
reaches 0.6 V typical. A direct/sustained short circuit will
cause the switch to pulse on for typically less than 1 µs, then
turn off. The switch turns on after 5 ms. If the short circuit
condition remains, the switch turns off and on to produce
a pulsed output. The current limiting circuitry is not
instantaneous, and therefore will not activate when the output charges a small 0.1 µF capacitor.
Built on Vishay Siliconix’s proprietary sub-micron high-density process, the DG2520/DG2521 brings low power consumption at the same time as reduces PCB spacing with the
TSOP6 package

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 termination, the lead (Pb)-free “- E3” suffix is being used as a designator.

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.
