CAPACITIVE CHARACTERISTICSCPDis definedas thevalueoftheIC’s internal equivalent capacitance whichis calculated fromthe operating current consumption without
load. (RefertoTest Circuit). Average operating currentcanbe obtained bythe following equation. ICC(opr) =CPD xVCCxfIN +ICC
TEST CIRCUIT=50pFor equivalent (includesjigand probe capacitance) =ZOUTof pulse generator (typically50Ω)
