Times are specified with loads of 1.35 k pull-up resistance and 57 pF load capacitance on the B side, and 167
and 57 pF load capacitance on the A side. Different load resistance and capacitance will alter the RC time constant, thereby changing
the propagation delay and transition times.
Pull-up voltages are V
Typical values were measured with V

The proportional delay data from A side to B side is measured at 0.3V
Defined as the time required to connect from B side to A side, after B side switches from active to idle, when A side is idle.
Defined as the time required to connect from B side to A side, when B side and A side are idle.
Defined as the time required to connect A side to B side, when B side is idle and A side is going active from idle, by a STOP condition.
