Times are specified with loads of 1.35 k pull-up resistance and 57 pF load capacitance on port B, and 450
57 pF load capacitance on port A. 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 t
The proportional delay data from port A to port B is measured at 0.3V
The enable pin, EN, should only change state when the global bus and the repeater port are in an idle state.
