For operating at elevated temperatures, devices in the H08 package must be derated based on a thermal resistance of 155 §C/W, junction to ambient, or 20 §C/W, junction to case. Note 2: For supply voltage less than g40V for the LM143 and less than g34V for the LM343, the absolute maximum input voltage is equal to the supply voltage. Note 3: These specifications apply for V S e g28V. For LM143, T A e max e 125§C and T A e min eb 55§C. For LM343, T A e max e 70§C and T A e min e 0§C. Note 4: Refer to RETS143X for LM143H and LM1536H military specifications. Note 5: The maximum supply currents are guaranteed at V S e g40V for the LM143 and V S e g34V for the LM343.
