ABSOLUTE MAXIMUM RATINGS
NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
2. The input and output negative-voltage ratings may be exceeded if the input and output
3. The maximum package power dissipation is calculated using a junction temperature
CAPACITANCE
NOTE:
1. Unused inputs must be held high or low to prevent them from floating.
