Note 4: Parameter guaranteed by design. tOSLH = |tPLH max − tPLH min|; tOSHL = |tPHL max − tPHL min|
Note 5: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average
operating current can be obtained by the equation: ICC (opr.) = CPD * VCC * fIN + ICC/8 (per Latch). The total CPD when n pcs. of the Latch operates can be
calculated by the equation: CPD(total) = 21 + 8n.
