NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation of
the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
2. The maximum package power dissipation is calculated using a junction temperature
of 150
°C and a board trace length of 750 mils.
3. The input and output negative-voltage ratings may be exceeded if the input and output
clamp-current ratings are observed. This value is limited to 2.5V max.
