Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its rated operating conditions.
Note 2: When the input voltage (V
maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of 5 mA to four.
Note 3: Reflow temperature profiles are different for lead-free and non-lead-free packages.
Note 4: Human body model, 100 pF discharged through a 1.5 kΩ resistor. Machine model, 200 pF discharged directly into each pin. The Charged Device Model
(CDM) is a specified circuit characterizing an ESD event that occurs when a device acquires charge through some triboelectric (frictional) or electrostatic induction
processes and then abruptly touches a grounded object or surface.
Note 5: LM75 θ

Note 6: All part numbers of the LM75 will operate properly over the +V
at their nominal supply voltage. Accuracy will typically degrade 1°C/V of variation in +V
Note 7: Limits are guaranteed to National's AOQL (Average Outgoing Quality Level).
Note 8: The conversion-time specification is provided to indicate how often the temperature data is updated. The LM75 can be accessed at any time and reading
the Temperature Register will yield result from the last temperature conversion. When the LM75 is accessed, the conversion that is in process will be interrupted
and it will be restarted after the end of the communication. Accessing the LM75 continuously without waiting at least one conversion time between communications
will prevent the device from updating the Temperature Register with a new temperature conversion result. Consequently, the LM75 should not be accessed
continuously with a wait time of less than 300 ms.
Note 9: For best accuracy, minimize output loading. Higher sink currents can affect sensor accuracy with internal heating. This can cause an error of 0.64°C at
full rated sink current and saturation voltage based on junction-to-ambient thermal resistance.
Note 10: O.S. Delay is user programmable up to 6 “over limit” conversions before O.S. is set to minimize false tripping in noisy environments.
Note 11: Default values set at power up.
Note 12: Typicals are at T
Note 13: Holding the SDA line low for a time greater than t
(SDA set High).
