(1) 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 under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
3.2 RECOMMENDED OPERATING CONDITIONS
T_A = –40°C to 85°C; 2.4 V < V_CC < 2.6 V; Typical values at T_A = 25°C and V_CC = 2.5 V (unless otherwise noted)
