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
CC
), 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.
Parasitic components and or ESD protection circuitry are shown in the figure below for the LM82’s pins. The nominal breakdown voltage of the zener D3 is 6.5 V.
Care should be taken not to forward bias the parasitic diode, D1, present on pins: D+, D,ADD1 andADD0. Doing so by more than 50 mV may corrupt a temperature
or voltage measurement.

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 Semicon-
ductor 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:
Thermal resistance of the QSOP-16 package is 130C/W, junction-to-ambient when attached to a FR-4 printed circuit board with 1 oz. foil as shown in Fig-
ure 3 .
