NOTES
1 See AC Timing Waveforms for waveforms and definition
2 Measure at V_IH for high time V_IL for low time
3 Only required to guarantee I_CC Maximum limits are bounded by T_C T_CH and T_CL
4 Specified for a 50 pF load see Figure 14 for capacitive derating information
5 Specified for a 50 pF load see Figure 15 for rise and fall times outside 50 pF
