These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(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.
(2) When the input voltage (V
I
) at any pin exceeds the power supplies (V
I
< GND or V
I
> +V
S
) the current at that pin should be limited to 5
mA. The 20 mA 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.
(3) See AN-450 “Surface Mounting Methods and Their Effect on Product Reliability” or the section titled “Surface Mount” found in a current
Texas Instruments Linear Data Book for other methods of soldering surface mount devices.
(4) Human body model, 100 pF discharged through a 1.5 kΩ resistor. Machine model, 200 pF discharged directly into each pin.

(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.
(2) LM76 θ
JA
(thermal resistance, junction-to-ambient) when attached to a printed circuit board with 2 oz. foil is 200°C/W.
(3) While the LM76 has a full-scale-range in excess of 128°C, prolonged operation at temperatures above 125°C is not recommended.
(4) The LM76 will operate properly over the +V
S
supply voltage range of 3V to 5.5V for the LM76CNM-3 and the LM76CHM-5. The
LM76CNM-3 is tested and specified for rated accuracy at the nominal supply voltage of 3.3V. Accuracy of the LM76CNM-3 will degrade
0.2°C for a ±1% variation in +V
S
from the nominal value. The LM76CHM-5 is tested and specified for a rated accuracy at the nominal
supply voltage of 5.0V. Accuracy of the LM76CHM-5 will degrade 0.08°C for a ±1% variation in +V
S
from the nominal value.
