Set-up and hold times are shown as positive values but may be specified as negative values.
The shaded areas indicate when the input is permitted to change for predictable output performance.
Logic levels: V
OL
and V
OH
are typical output voltage levels that occur with the output load.
Measurement points are given in Table 9
.
