AC Electrical Characteristics
Notes:
3. Parameter guaranteed by design tOSLH = |tPLHmax – tPLHmin|; tOSHL = |tPHLmax – tPHLmin|.
4. 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 / 8 (per F/F). The total CPD when n pieces of the Flip-Flop operates can be
calculated by the equation: CPD (total) = 22 + 9n.
AC Operating Requirements
Note:
5. VCC is 3.3 ± 0.3V or 5.0 ± 0.5V
