(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) The THS3122 and THS3125 may incorporate a PowerPAD on the underside of the chip. This pad acts as a heatsink and must be
connected to a thermally dissipating plane for proper power dissipation. Failure to do so may result in exceeding the maximum junction
temperature which could permanently damage the device. See TI Technical Brief SLMA002 for more information about utilizing the
PowerPAD thermally-enhanced package.
