Logic Electrical Characteristics
(Continued)
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
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.
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 k
resistor. Machine model, 200 pF discharged directly into each pin.
Note 5:
The life expectancy of the LM71 will be reduced when operating at elevated temperatures. LM71

Note 6:
The LM71 will operate properly over the V
+
supply voltage range of 2.65V to 5.5V.
Note 7:
Typicals are at T
A
= 25C and represent most likely parametric norm.
Note 8:
Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 9:
This specification is provided only to indicate how often temperature data is updated. The LM71 can be read at any time without regard to conversion state
(and will yield last conversion result). A conversion in progress will not be interrupted. The output shift register will be updated at the completion of the read and a
new conversion restarted.
Note 10:
For best accuracy, minimize output loading. Higher sink currents can affect sensor accuracy with internal heating. This can cause an error of 0.64C at full
rated sink current and saturation voltage based on junction-to-ambient thermal resistance.
