Notes:
1. All electrical specifications in the above table are specified with 15 pF output load and for all Vdd(s) unless otherwise stated.
2. The typical value of any parameter in the Electrical Characteristics table is specified for the nominal value of the highest voltage option for that parameter and at
25°C temperature.
3. All max and min specifications are guaranteed across rated voltage variations and operating temperature ranges, unless specified otherwise
4. Initial tolerance is measured at Vin = Vdd/2
5. Absolute Pull Range (APR) is defined as the guaranteed pull range over temperature and voltage.
6. APR = pull range (PR) - frequency stability (F_stab) - Aging (F_aging)
