dards JESD51-2 and JESD51-6, and the junction-to-board
measurement complies with JESD51-8. The junction-to-case
measurement complies with MIL-STD-883 (Method 1012.1).
All measurements use a 2S2P JEDEC test board.
The LQFP_EP package requires thermal trace squares and ther-
mal vias to an embedded ground plane in the PCB. The paddle
must be connected to ground for proper operation to data sheet
specifications. Refer to JEDEC standard JESD51-5 for more
information.
