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.
