Figure 13 - Clock Timing
Timing is over recommended temperature & power supply voltages
Typical figures are at 25
°
C and are for design aid only: not guaranteed and not subject to production testing.
* High Impedance is measured by pulling to the appropriate rail with R
L
, with timing corrected to cancel time taken to discharge C
