NOTE: Timing for Figures 1, 2, and 3 are design estimates only.
* For a time (t = 4/OSC FREQ.) after the backplane waveform changes to a new voltage level, the circuit is maintained in the high–current state
to allow the load capacitances to charge quickly. The circuit is then returned to the low–current state until the next voltage change.
