9) This indicates the time taken between power-up and the outputs becoming active. An on-chip delay is
10) Output voltage swings can be impaired at high frequencies combined with high-output loading.
11) After this period, the first clock pulse is generated.
12) A device must internally provide a hold time of at least 300ns for the SDA signal (referred to the

16) EEPROM write begins after a STOP condition occurs.
17) Typical frequency shift due to aging is ±0.5%. Aging stressing includes Level 1 moisture reflow
