Product details

USB 3.1 hub controller for downstream port expansion

The TUSB8044ARGCT is a USB 3.1 hub controller for downstream port expansion. It communicates over I²C and SMBus, and is housed in a 64-VQFN (9x9) package with an exposed pad.

Commercial temperature grade — indoor use only

Rated for 0°C to 70°C ambient, this part is specced for commercial environments. It is not qualified for industrial or automotive temperature ranges.

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).
