II VI = 5.5V or GND 0V to 5.5V ±1 µA
ICC VI = VCC or GND, IO = 0 5.5V 2 µA
ΔICC VI = VCC – 2.1V; Any Input 4.5V to 5.5V 200 µA
CI VI = VCC or GND 5V 2 pF
CPD(1)(2) CL = 50pF, F = 1MHz 5V 57 pF
(1) CPD is used to determine the dynamic power consumption, per channel
(2) PD= VCC2xFIx(CPD+ CL) where FI= input frequency, CL= output load capacitance, VCC= supply voltage
(3) Not more than one output should be tested at a time, and the duration of the test should not exceed 2 ms.
