Note 1: Absolute Maximum Ratings
indicate limits beyond which damage to the device may occur.
Operating Ratings
indicate conditions for which the device
is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics.
The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the
listed conditions.
Note 2:
The Human Body model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin. The machine model is a 200pF capacitor discharged
directly into each pin.
Note 3:
The maximum allowable power dissipation is a function of the maximum junction temperature, T
J
(MAX), the junction-to-ambient thermal resistance,
θ
J-A
,
and the ambient temperature, T
A
. The maximum allowable power dissipation at any ambient temperture is calculated using:
Where the value of
θ
J-A
for the MSOP-10 package is 195C/W in a typical PC board mounting and the micro SMD package is 220C/W.
