AC Electrical Characteristics
AC Chip Level Specifications
Table 17, Table 18, and Table 19 list the guaranteed maximum and minimum specifications for the voltage and temperature ranges:
4.75V to 5.25V and -40°C ≤ T_A ≤ 85°C, 3.0V to 3.6V and -40°C ≤ T_A ≤ 85°C, or 2.4V to 3.0V and -40°C ≤ T_A ≤ 85°C respectively.
Typical parameters apply to 5V, 3.3V, or 2.7V at 25°C. These are for design guidance only.
