Note 4: Max number of outputs defined as (n). Data inputs are driven 0V to VCC level; one output at GND.
Note 5: Max number of Data Inputs (n) switching. (n−1) inputs switching 0V to VCC level. Input-under-test switching:
VCC level to threshold (VIHD), 0V to threshold (VILD), f = 1 MHz.

Note 6: Voltage Range 3.3V is 3.3V ± 0.3V.
Note 7: Voltage Range 5.0V is 5.0V ± 0.5V.
Note 8: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The
specification applies to any outputs switching in the same direction, either HIGH-to-LOW (tOSHL) or LOW-to-HIGH (tOSLH). Parameter guaranteed by design.
