(i sink ), while logic highs are ?let go? (3-state). for example, when the master lets go of scl (scl always comes from the master), the rise time of scl is largely determined by the rc time constant, where r = r pu and c = the bus capacitance. if th e FXMAR2102 is attached to the master [on the a port] and there is a slave on the b port, the npassgates act as a low-resistive short between both ports until ei ther of the port?s v cc /2 thresholds are reached. after the rc time constant has reached the v cc /2 threshold of either port, the port?s edge detector triggers both dynamic drivers to drive their respective ports in the low-to-high (lh) direction, accelerating the rising edge. the resulting rise time resembles the scope shot in figure 5. effectively, two distinct slew rates appear in rise time. the first slew rate (slower) is the rc time constant of the bus. the second slew rate (much faster) is the dynamic driver accelerating the edge. if both the a and b ports of the translator are high, a high-impedance path exists between the a and b ports because both the n passgates are turn ed off. if a master or slave device decides to pull scl or sda low, that device?s driver pulls down (i sink ) scl or sda until the edge reaches the a or b port v cc /2 threshold. when either the a or b port threshold is reached, the port?s edge detector triggers both dynamic drivers to drive their respective ports in the high-to-low (hl) direction, accelerating the falling edge. figure 5. waveform c: 600pf, total r pu : 2.2k ?
