Package and rework — what the 40-WQFN means at the bench
This part lives in a 40-pin WFQFN with an exposed thermal pad, body size 6x4 mm. The pad is the main heat path and the ground return — it needs a solid solder joint to the board's thermal land.
Lifecycle and sourcing — active, no LTB clock ticking
TI lists the TUSB1064RNQT as active. No NRND flag, no last-time-buy notice. For a BOM freeze, that means no forced redesign cycle from this line item. The part is ROHS3 compliant, so no exemption-expiry concern on the compliance side.
