... Bus Rising Edge Waveform When all external pull-downs on SCL1 (Figure 1) turn off, the SCL1 rising waveform will resemble that shown in Figure 4. The LTC4310-1 senses that SCL1 is rising and transmits a message to the other LTC4310-1 to release SCL2 high. During the transmission, the first LTC4310-1 also drives SCL1 to 0 ...
