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. VCC(L) must always be less than or equal to VCC(H)
2. The THS6032 incorporates a PowerPAD on the underside of the chip. This acts as a heatsink and must be connected to a thermally
dissipative plane for proper power dissipation. Failure to do so may result in exceeding the maximum junction temperature which
could permanently damage the device. See the Thermal Information section for more information about utilizing the PowerPAD
thermally enhanced packages.
