... NXP Semiconductors 8. Functional description Refer to 8.1 Start-up An undervoltage and initialization circuit holds the parts in a disconnected state which presents high-impedance to all SDAn and SCLn pins during power-up. A LOW on the ENABLE pin also forces the parts into the low current disconnected state when the I essentially zero ...

... NXP Semiconductors 8.3 Maximum number of devices in series Each buffer adds about 0.1 V dynamic level offset with the offset larger at higher temperatures. Maximum offset (V level at the signal origination end (master) is dependent upon the load and the only specification point is the I lightly loaded the V after four buffers would be 0 ...

... NXP Semiconductors 8.4 Propagation delays The delay for a rising edge is determined by the combined pull-up current from the bus resistors and the rise time accelerator current source and the effective capacitance on the lines. If the pull-up currents are the same, any difference in rise time is directly proportional to the difference in capacitance between the two sides ...
