(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.
(3) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, RθJA, and the ambient temperature,
TA. The maximum allowable power dissipation at any temperature is PD = (TJMAX − TA) / RθJA, or the number given in the Absolute
Maximum Ratings, whichever is lower. The maximum junction temperature, TJMAX, for the LF198-N and LF198A-N is 150°C; for the
LF298, 115°C; and for the LF398-N and LF398A-N, 100°C.
(4) Although the differential voltage may not exceed the limits given, the common-mode voltage on the logic pins may be equal to the
supply voltages without causing damage to the circuit. For proper logic operation, however, one of the logic pins must always be at least
2 V below the positive supply and 3 V above the negative supply.
