AC Electrical Characteristics
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) = 21 + 8n.
