Note: Event Interrupt mode is drawn as if the user is reading the part. If the user doesn't read, the outputs would go low and stay that way until the LM76 is read.
1.4 TEMPERATURE DATA FORMAT
Temperature data can be read from the Temperature and Set
Point registers; and written to the Set Point registers. Tem-
perature data can be read at any time, although reading faster
than the conversion time of the LM76 will prevent data from
being updated. Temperature data is represented by a 13-bit,
two's complement word with an LSB (Least Significant Bit)
equal to 0.0625°C:
