pF (Note 4) Figure 2
Note 4: CPD is defined as the value of the internal equivalent capacitance which is derived from dynamic operating 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) (ICC static)
