Hi,
I need to know the conditions considered for measuring the Rthja of "SN74AHC1G00QDCKRQ1"
- Board type used (is it FR4)
- Copper thickness of board in oz
- Pad layout: is it minimum recommended pad layout

Hi Harish,
The datasheet thermal metrics assume the JEDEC standard 2s2p (high-k) PCB, which is an FR4 four layer board. The thickness of the top and bottom layers is 2 oz Cu and the internal planes are 1 oz Cu. The trace layout is defined by JESD51-7 and is dependent on the package footprint.

Owen
