Notes:
3. Parameter guaranteed by design. tOSLH = |tPLH max – tPLH min |; tOSHL = |tPHL max – tPHL min|
4. 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) = 14 + 13n.
