1. The test conditions used are all four outputs switching simultaneously. The AC characteristics described above are also guaranteed when two
outputs are tied together.
2. Where tp On and tp Om are the actual propagation delays (any combination of high or low) for two separate outputs from a given high transition
of CP.
3. For a given set of conditions (i.e., capacitive load, temperature, VCC, and number of outputs switching simultaneously) the variation from device
to device is guaranteed to be less than or equal to the maximum.
