b. PL and MR recovery times, CPU, CPD, PL and MR minimum pulse widths, and Dn to PL 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 is where the data can change for predictable performance.
Measurement points are given in Table 9.
