Note 5: Parameter guaranteed by design. tOSLH = |tPLHmax − tPLHmin|; tOSHL = |tPHLmax − tPHLmin|.
Note 6: 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) + (ICCstatic).
