Times are specified with loads of 240 Ω ±1% and 400 pF ±10% on B-side and 240 Ω ±1% and 200 pF ±10% on A-side. Different load resistance and capacitance alter the rise time, thereby changing the propagation delay and transition times.
Times are specified with A-side signals pulled up to VCCA and B-side signals pulled up to VCCB.
Typical values were measured with VCCA = 0.9 V and VCCB = 2.5 V at TA = 25°C, unless otherwise noted.
TTLH is determined by the pull-up resistance and load capacitance

EN should change state only when the global bus and the repeater port are in an idle state
