AC/DC ELECTRICAL CHARACTERISTICS
(Cont
’
d)
1)The device must internally provide a hold time of at least 300 ns for the SDA signal in order to bridge the undefined
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
