7.3.2 Low to High Transition Characteristics (B to A)

Figure 7-1 depicts the offset voltage on the B side of the device. As shown in Figure 7-1 the target releases and the B-side rises, and rises to VOLB and stays there until the A-side rises above 30% of VCCA. This effect can cause the low level signal to have a pedestal. Once the voltage on the A-side crosses 30% of VCCA, the B-side begins to rise to VCCB.

Due to nature of the B-side pedestal and the static offset voltage, there is a slight overshoot as the B-side rises from being externally driven low to the VOLB offset.
