Average operating current can be obtained by the equation: ICC (opr) = CPD・VCC・fIN + ICC When the outputs drive a capacitive load, total current consumption is the sum of CPD, and ΔICC which is obtained from the following formula: In case of TC74HC161A/163A: ) 16 C 16 C 8 C 4 C 2 C ( V f I CO QD QC QB QA CC CK CC + + + + ⋅ = Δ CQA~CQD and CCO are the capacitances at QA~QD and CO, respectively. fCK is the input frequency of the CK.
