Webthe slow rise times resulting when bus capacitance is high. Rise times can be improved by using lower pull-up resistor values or higher ﬁ xed current source values, but the additional current increases the low state bus voltage, decreasing noise margins. Slow rise times can seriously impact data reliability, enforcing a maximum practical bus WebDec 15, 2024 · The maximum pull-up resistance is the function of the maximum rise time (tr). This is a very important equation because it is a function of rise time and bus capacity. Where tr means rise time of both SDA and SCL signals and Cb means capacitive load for each bus line. Rise time (tr): Consider the waveform in Figure 4. It can be either SDA or …
