SNIS109E – JANUARY 2000 – REVISED MARCH 2013

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.

TEMPERATURE DATA FORMAT

Temperature data can be read from the Temperature and Set Point registers; and written to the Set Point

registers. Temperature 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:
