This bus pull-up current specification is intended to assist design of the bus pull-up resistor. It is not a specification of the sink capability
(see V
PCA9600 is guaranteed to sink 3 mA at SX/SY when its pins are holding the bus LOW. However, when an external device pulls the
SX/SY pins below 1.4 V, the PCA9600 may source a current between 0 mA and 1 mA maximum. When that other external device is
driving LOW it will pull the bus connected to SX or SY down to, or below, the 0.4 V level referenced in the I
these test conditions. Then that device must be able to sink up to 1 mA coming from SX/SY plus the usual pull-up current. Therefore the
external pull-up used at SX/SY should be limited to 2 mA. The typical and maximum currents sourced by SX/SY as a function of junction
temperature are shown in

The input logic threshold is independent of the supply voltage.
The minimum value requirement for pull-up current, 0.3 mA, guarantees that the minimum value for V

IC. While the tolerances on absolute levels allow a small probability, the LOW from one SX output is recognized by an SX input of
another PCA9600, this has no consequences for normal applications. In any design the SX pins of different ICs should never be linked
because the resulting system would be very susceptible to induced noise and would not support all I
