5 / 9 page ©1993 Fairchild Semiconductor Corporation www.fairchildsemi.com 74VHC573 Rev. 1.3 5 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.
