SWITCHING CHARACTERISTICS TEST WAVEFORM
M54/M74HCT257/258
TEST CIRCUIT ICC (Opr.)
CPD CALCULATION
CPD is to be calculated with the following
formula by using the measured value of
ICC (opr.) in the test circuit opposite.
CPD
=
ICC (opr)
fIN × VCC
INPUT WAVEFORM IS THE SAME AS THAT IN CASE OF
SWITCHING CHARACTERSISTICS TESt.
