(2) If Military/Aerospace specified devices are required, contact the TI Sales Office/Distributors for availability and specifications.
(3) Unless otherwise specified the absolute maximum negative input voltage is equal to the negative power supply voltage.
(4) Max. Power Dissipation is defined by the package characteristics. Operating the part near the Max. Power Dissipation may cause the
part to operate outside specified limits.
