13. 0.4 VCC(A) + 0.8 V ≤ VCC(B) for the channels to be enabled and functional normally.
14. Times are specified with loads of 1.35 kW pull−up resistance and 50 pF load capacitance on port A and port B, and a falling edge slew rate
of 0.05 V/ns input signals.
15. Pull−up voltages are VCC(A) on the A side and VCC(B) on the B side.
16. Typical values were measured with VCC(A) = 0.95 V, VCC(B) = 2.5 V at TA = 25°C, unless otherwise noted.
17. The tPLH2 delay data from port B to port A is measured at 0.45 V on port B to 0.5 VCC(A) on port A.
18. The tTLH of the bus is determined by the pull−up resistance (1.35 kW) and the total capacitance (50 pF).
19. The proportional delay data from port A to port B is measured at 0.5 VCC(A) on port A to 0.5 VCC(B) on port B.
20. The enable pin, EN, should only change state when the global bus and the repeater port are in an idle state.
