PCA9517DGKR from Texas Instruments, in a MSOP-8. 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 5.5 V). Provides the 0.3 x VCCA reference used by the A-side comparators and the power-good detect circuit. |
| 2 | SCLA | bidirectional | Serial clock bus, A side (open-drain). Connect to VCCA through an external pullup resistor. |
| 3 | SDAA | bidirectional | Serial data bus, A side (open-drain). Connect to VCCA through an external pullup resistor. |
| 4 | GND | power_in | Supply ground reference (0 V). |
| 5 | EN | input | Active-high repeater enable input. Internally pulled up to VCCB; drive low to disable the repeater and isolate the two buses. Should only change state when the bus is idle. |
| 6 | SDAB | bidirectional | Serial data bus, B side (open-drain). Connect to VCCB through an external pullup resistor. |
| 7 | SCLB | bidirectional | Serial clock bus, B side (open-drain). Connect to VCCB through an external pullup resistor. |
| 8 | VCCB | power_in | B-side and device supply voltage (2.7 V to 5.5 V). Powers the PCA9517 logic and all I/Os. |
