ELECTRICAL CHARACTERISTICS (Cont’d)
Bus free time between a STOP and START con-
dition
Hold time START condition. After this period,
LOW period of the SCL clock
HIGH period of the SCL clock
Set-up time for a repeated START condition
Data hold time
Data set-up time
Rise time of both SDA and SCL signals
Fall time of both SDA and SCL signals
Set-up time for STOP condition
Capacitive load for each bus line
the first clock pulse is generated
1)The device must internally provide a hold time of at least 300 ns for the SDA signal in order to bridge the unde-
fined region of the falling edge of SCL
2)The maximum hold time of the START condition has only to be met if the interface does not stretch the low period
of SCL signal
Cb = total capacitance of one bus line in pF
