Capacitance
pF
(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(RefertoTestCircuit). Average operting current canbeobtained by the following equation. ICC(opr) =CPD •VCC •fIN +ICC’ Duty/100 + IC/2 (per monostable)
(ICC’: Active Supply Current) (Duty:%)
