These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Package Information8 TDFN Package Code T823+1C Outline Number 21-0174 Land Pattern Number 90-0091 Thermal Resistance, Four-Layer Board: Junction-to-Ambient (θJA) 60°C/W Junction-to-Case Thermal Resistance (θJC) 11°C/W 8 WLP Package Code W61L1+1 Outline Number 21-100365 Land Pattern Number Refer to Application Note 1891 Thermal Resistance, Four-Layer Board: Junction-to-Ambient (θJA) 81.03°C/W Junction-to-Case Thermal Resistance (θJC) N/A For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a “+”, “#”, or “-” in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing pertains to the package regardless of RoHS status. Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.
