Logic Electrical Characteristics
DIGITAL DC CHARACTERISTICS Unless otherwise noted, these specifications apply for +V
LM75BIMM-5, LM75CIM-5, and LM75CIMM-5 and +V
LM75CIMM-3 (Note 6). Boldface limits apply for T
noted.
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 exceedthe power supplies with an input current of 5 mA to four.
Note 3: See AN-450 “Surface Mounting Methods and Their Effect on Product Reliability” or the section titled “Surface Mount” found in a current National
Semiconductor Linear Data Book for other methods of soldering surface mount devices.
Note 4: Human body model, 100 pF discharged through a 1.5 kΩ resistor. Machine model, 200 pF discharged directly into each pin.
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).
