(Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/4 (per gate) DYNAMIC SWITCHING CHARACTERISTICS 1) Worst case package. 2) Max number of outputs defined as (n). Data inputs are driven 0V to 5.0V, (n-1) outputs switching and one output at GND. 3) Max number of data inputs (n) switching. (n-1) switching 0V to 5.0V. Inputs under test switching: 5.0V to threshold (VILD), 0V to threshold (VIHD), f=1MHz. Symbol Parameter Test Condition Value Unit TA = 25°C -40 to 85°C -55 to 125°C Min. Typ. Max. Min. Max. Min. Max.
