Note 1:

Note 4:
All voltages are referenced to ground.
The value of V
DD
should never exceed V
CC
, including during power-ups. V
CC
must be applied before V
DD
.
I
DD
is specified with SDA = SCL =
CE
= V
DD
, resistor pins floating, and digital inputs connected to V
DD
or GND.
I
CC
is specified with SDA = SCL =
CE
= V
DD
, resistor pins floating, and digital inputs connected to V
DD
or GND, after zero-
crossing detection has timed out.
The DS1881 will not obstruct the SDA and SCL lines if V
DD
is switched off as long as the voltages applied to these inputs
do not violate their minimum and maximum input voltage levels.
Guaranteed by design.
Above Position 50, these are typical maximum. Guaranteed by characterization.
Load is representative of the input of a low-noise audio amp.
Timing shown is for fast-mode (400kHz) operation. This device is also backward-compatible with I
2
C standard-mode timing.
Note 10:
C
B
—Total capacitance of one bus line in picofarads.
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.
