DESCRIPTION
This parameter is sampled.
Test conditions as specified with the output loading as shown in Fig. 1 unless otherwise noted.
Output loading is specified with CL=5pF as in Fig. 2.
At any given temperature and voltage condition,
This is a synchronous device. All synchronous inputs must meet specified setup and hold time, except for “don’t care” as defined in the
truth table.
