All voltages are referenced to ground, unless otherwise noted.
2.
Logic 0 voltage specified at a sink current of 4 mA at V

DD
≤
5.5V. Accuracy will degrade approximately
0.5°C if ALRM is sinking the maximum current.
7.
Thermometer resolution (in °C) = 1/COUNT_PER_C(T). The calibration algorithm is such that
COUNT_PER_C and thus resolution varies over temperature (but is constant at a given
temperature for a given device) and from device to device.
