Note 5: The DS1881 will not obstruct the SDA and SCL lines if V  
is switched off as long as the voltages applied to these inputs

do not violate their minimum and maximum input voltage levels.  
Note 6: Guaranteed by design.  
Note 7: Above Position 50, these are typical maximum. Guaranteed by characterization.  
Note 8: Load is representative of the input of a low-noise audio amp.  
Note 9: Timing shown is for fast-mode (400kHz) operation. This device is also backward-compatible with I C standard-mode timing.

Note 11: If zero-crossing detection is enabled, the EEPROM write does not begin until the current zero-crossing detection is com-  
plete. Otherwise, EEPROM write begins after a STOP condition occurs.
