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 by the equation:
ICC (opr) = CPD VCC fIN + ICC
When the outputs drive a capacitive load, total current consumption is the sum of CPD, and ICC which is obtained
from the following formula:
CQ0–CQ3 and CTC are the capacitances at Q0–Q3 and TC, respectively. FCP is the input frequency of the CP.
