AC Electrical Characteristics
Note:
3. CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating
current consumption without load. Average operating current can be obtained from the equation:
ICC (opr.) = CPD VCC fIN + ICC / 2 (per F/F).
AC Operating Requirements
Note:
4. VCC is 3.3 ± 0.3V or 5.0 ± 0.5V
