(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 the network ground terminal.
(3) Maximum power dissipation is a function of T

(4) The package thermal impedance is calculated in accordance with JESD 51-7.
(5) RS-232 pins are tested with respect to ground and to each other.
(6) Per MIL-PRF-38535
(7) RS-232 pins are tested with respect to ground.
