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

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

biased 125°C HTOL, 1000 temperature cycles at -55°C to +125°C, and 168hr 121°C/2 ATM Steam/Unbiased Autoclave.
