AC Electrical Characteristics (Over Operating Range, TA = –40°C to +85°C)
Notes:
7. 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, CPD is related to ICCD dynamic operating current by the expression: ICCD = (CPD)(VCC)(fIN)
+(ICC static)
Note:
8. Skew between any two outputs of the same device, switching in the same direction. Parameter guaranteed by design.
