TCA9517DGKRQ1 from Texas Instruments, in a VSSOP-8-0.65mm. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCCA | power_in | A-side supply voltage (0.9 V to 5.25 V). Provides the 0.3 x VCCA reference for the A-side input comparators and powers the A-side supply-good detect. |
| 2 | SCLA | bidirectional | Serial clock bus, A-side. Open-drain; connect to VCCA through a pull-up resistor. If unused, connect directly to ground. |
| 3 | SDAA | bidirectional | Serial data bus, A-side. Open-drain; connect to VCCA through a pull-up resistor. If unused, connect directly to ground. |
| 4 | GND | power_in | Device ground reference. |
| 5 | EN | input | Active-high repeater enable input. Referenced to VCCB (VIH >= 0.7 x VCCB, VIL <= 0.3 x VCCB). Should only change state when both the global bus and repeater port are idle; setup/hold to Start/Stop = 100 ns. |
| 6 | SDAB | bidirectional | Serial data bus, B-side. Open-drain; connect to VCCB through a pull-up resistor. If unused, connect directly to ground. |
| 7 | SCLB | bidirectional | Serial clock bus, B-side. Open-drain; connect to VCCB through a pull-up resistor. If unused, connect directly to ground. |
| 8 | VCCB | power_in | B-side and device supply voltage (2.7 V to 5.25 V). Powers all internal logic and I/O; also the reference for EN and B-side input thresholds. |
