† _{Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and}
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values are with respect to network terminal ground.
2. Refer to Figures 1 and 2 to avoid exceeding the design maximum virtual junction temperature; these ratings should not be exceeded.
Due to variation in individual device electrical characteristics and thermal resistance, the built-in thermal overload protection may
be activated at power levels slightly above or below the rated dissipation.

‡ _{RθJP is the thermal resistance between the junction and the device pin. To determine the virtual junction temperature (TJ) relative to the device}
pin temperature, the following calculations should be used: TJ = PD x R_θJP + TP, where PD is the internal power dissipation of the device and TP
is the device pin temperature at the point of contact to the printed wiring board. The R_θJP for the TL75LPxx series is 50.5°C/W.
