CO VO = VCC or GND 5V 4.1 pF
CPD(1)(2) CL = 50pF, F = 1MHz 5V 30 pF
CPD is used to determine the dynamic power consumption, per channel
PD= VCC2xFIx(CPD+ CL) where FI= input frequency, CL= output load capacitance, VCC= supply voltage
Not more than one output should be tested at a time, and the duration of the test should not exceed 2 ms.
