High-to-Low Transition Characteristics

When the A side of the bus is driven to 30% of VCCA, the B side driver turns on. This drives the B-side to 0V for a short period (see Figure 6-2), and then the B-side rises to the static offset voltage of 0.5V (VOL of TCA9617B). This effect, called an inverted pedestal, allows the B-side to drive to logic low much faster than driving to the static offset. Driving to the static offset voltage requires that the fall time be slowed to prevent ringing.
