CAPACITIVE CHARACTERISTICS
1) 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/16(per
circuit)
DYNAMIC SWITCHING CHARACTERISTICS
1) Worst case package.
2) Max number of outputs defined as (n). Data inputs are driven 0V to 3.3V, (n-1) outputs switching and one output at GND.
3) Max number of data inputs (n) switching. (n-1) switching 0V to 3.3V. Inputs under test switching: 3.3V to threshold (VILD), 0V to threshold
(VIHD), f=1MHz.
