4 / 13 page 74LVX574 4/13 Table 7: 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. Table 8: AC Electrical Characteristics (Input tr = tf = 3ns) 1) Skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs of the same device switch- ing in the same direction, either HIGH or LOW 2) Parameter guaranteed by design (*) Voltage range is 3.3V ± 0.3V Symbol Parameter Test Condition Value Unit VCC (V) TA = 25°C -40 to 85°C -55 to 125°C Min.
