(1) 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.
(2) All voltages are with respect to network GND.
(3) Maximum power dissipation is a function of T_J(max), θ_JA, and T_A. The maximum allowable power dissipation at any allowable ambient
temperature is P_D = (T_J(max) – T_A)/θ_JA. Operating at the absolute maximum T_J of 150°C can affect reliability.
(4) The package thermal impedance is calculated in accordance with JESD 51-7.

(1) Testing supply conditions are C1–C4 = 0.1 μF at V_CC = 3.3 V ± 0.15 V; C1–C4 = 0.22 μF at V_CC = 3.3 V ± 0.3 V; and C1 = 0.047 μF
and C2–C4 = 0.33 μF at V_CC = 5 V ± 0.5 V.
