2. Electrical Characteristics
2.1. ESD Notice
The SX1242 is a high performance radio frequency device, and satisfies Class 2 of the JEDEC
standard JESD22-A114-B (human body model) on all pins.
It should thus be handled with all necessary ESD precautions to avoid any permanent damage.
2.2. Absolute Maximum Ratings
Stresses above the values listed below may cause permanent device failure. Exposure to absolute maximum ratings for
extended periods may affect device reliability.
