5 / 9 page ©1992 Fairchild Semiconductor Corporation www.fairchildsemi.com 74VHC240 Rev. 1.3 5 AC Electrical Characteristics Notes: 3. Parameter guaranteed by design. tOSLH = |tPLHmax – tPLHmin|; tOSHL = |tPHLmax – tPHLmin| 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 bit). Symbol Parameter VCC (V) Conditions TA = 25°C TA = –40°C to +85°C Units Min. Typ. Max.
