2. Electrical Characteristic
2.1. ESD and Latchup Notice
The SX1781 is a high performance radio frequency device. It withstands:
2 kV ESD discharge with the Human Body Model (Class 2 of the JEDEC standard JESD22-A114-B)
1 kV ESD discharge with the Charged Device Model (Class IV of JESD22-C101C)
+/- 100 mA Static Latchup current at maximum temperature (Class II Level A of JESD78)
It should be handled with all the necessary ESD precautions to avoid any permanent damage.
2.2. Maximum Ratings
Important Note: The Absolute Maximum Ratings, in Table 1, are stress ratings only, and functional operation of the device
at conditions other than those indicated in the Operating Conditions sections of this specification are not implied. Exposure
to the absolute maximum ratings, where different to the operating conditions, for an extended period may reduce the
reliability or useful lifetime of the product.
