Note 3: CPD is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current. Current consumption (ICCD) at
no output loading and operating at 50% duty cycle. (See Figure 2). CPD is related to ICCD dynamic operating current by the expression:
ICCD = (CPD)(VCC)(fIN) + (ICCstatic).
