12-stage binary ripple counter
11. Waveforms
Logic levels: VOL and VOH are typical output voltage levels that occur with the output load.
Transition times: transition time (tt) = HIGH LOW (tTHL) or LOW HIGH (tTLH) transition times.
Measurement points are given in Table 8, test circuit in Figure 6 and test data in Table 9
