b. CP and MR minimum pulse widths, MR to CP recovery time, and Dn to CP set-up and hold times
VOH and VOL are typical output voltage levels that occur with the output load.
Set-up and hold times are shown as positive values but may be specified as negative values.
The shaded area are where input changes result in predicable output performance.
Measurement points are given in Table 9.
