4.2 Timing Parameter Symbology and Load Conditions
The timing parameter symbols have been created following one of the following formats:
4.2.1 TIMING CONDITIONS
The temperature and voltages specified in Table 4- 2 apply to all timing specifications, unless otherwise noted.
Figure 4-2 specifies the load conditions for the timing specifications.
