Frequently asked questions
Does TUSB8044ARGCT support USB 3.1 Gen 2 or only Gen 1?
The TUSB8044ARGCT is specified as a USB 3.1 hub controller. The evidence does not distinguish Gen 1 from Gen 2; verify the exact data rate support in the full datasheet.
What is the TUSB8044ARGCT replacement or equivalent part?
The TUSB8044ARGCR is the same die in a different reel format (Cut Tape / Digi-Reel vs Tape & Reel). The CT/TR suffix is the only delta — same function, same supply rails, same temperature range.
Is TUSB8044ARGCT compatible with USB 3.0?
The part is specified as USB 3.1. USB 3.1 is backward-compatible with USB 3.0 at the protocol level; the hub will enumerate USB 3.0 devices at SuperSpeed (5 Gbps).
