Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is func-
tional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed speci-
fications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions.
Note 2:
When the input voltage (V
I
) at any pin exceeds the power supply (V
I
<
GND or V
I
>
V
+
), the current at that pin should be limited to 5 mA. The 20 mA maxi-
mum 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:
The maximum power dissipation must be derated at elevated temperatures and is dictated by T
Jmax
(maximum junction temperature),
JA
(junction to am-
bient thermal resistance) and T
A
(ambient temperature). The maximum allowable power dissipation at any temperature is P
D
= (T
Jmax
鈥揟
A
)/胃
JA
or the number given
in the Absolute Maximum Ratings, whichever is lower. For this device, T
Jmax
= 125藲C. For this device the typical thermal resistance (胃
JA
) of the different package
types when board mounted follow:
Package Type
M08A
JA
110藲C/W
Note 4:
The human body model is a 100 pF capacitor discharge through a 1.5 k鈩?resistor into each pin. The machine model is a 200 pF capacitor discharged directly
into each pin.
Note 5:
See AN450 鈥淪urface Mounting Methods and Their Effects on Product Reliability鈥?or the section titled 鈥淪urface Mount鈥?found in any post 1986 National Semi-
conductor Linear Data Book for other methods of soldering surface mount devices.
Note 6:
Typicals are at T
J
= T
A
= 25藲C and represent most likely parametric norm.
Note 7:
Limits are guaranteed to National鈥檚 AOQL (Average Outgoing Quality Level).
