COMMUNICATION INTERFACE CHARACTERISTICS (Cont’d)
13.11.3 I
1) The device must internally provide a hold time of at least 300 ns for the SDA signal in order to bridge
2) The maximum hold time of the START condition has only to be met if the interface does not stretch the
Cb = total capacitance of one bus line in pF
146/161
Bus free time between a STOP and START con-
dition
Hold time START condition. After this period,
