5 / 15 page M74HC4851 5/15 AC ELECTRICAL CHARACTERISTICS (CL = 50 pF, Input tr =tf =6ns) (*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) =CPD xVCC xfIN +ICC/8 INJECTION CURRENT COUPLING SPECIFICATION (TA= -55°C to +125°C) 1) Typical values are measured at TA=25°C e they are calculate as difference from VOUT without Injection Current and VOUT with Injection Current. IIN = total current injected into any other disabled channels, one at time. Symbol Parameter Test Condition Value Unit VCC (V) TEST CIRCUIT 1 TA = 25°C up to 85°C up to 125°C Min. Typ. Max. Min. Max.
