Note 1: All voltages referenced to ground.
Note 2: This is the change observed in output frequency due to changes in temperature or voltage.
Note 3: This is a percentage of the output period. Parameter is characterized but not production tested. This can be varied from
2%, 4%, or 8%.
Note 4: This parameter is guaranteed by design.
Note 5: This indicates the time between power-up and the outputs becoming active. An on-chip delay is intentionally introduced to
allow the oscillator to stabilize. t STAB is equivalent to approximately 64 f MOSC cycles and, hence, will depend on the pro-
grammed clock frequency.
Note 6: Timing shown is for fast-mode (400kHz) operation. This device is also backward compatible with I 2 C standard-mode timing.
Note 7: CB—total capacitance of one bus line in picofarads.
Note 8: Typical frequency shift due to aging is ±0.5%. Aging stressing includes Level 1 moisture reflow preconditioning (24hr
+125°C bake, 168hr 85°C/85%RH moisture soak, and 3 solder reflow passes +240 +0/-5°C peak) followed by 1000hr max
