PCA9517DR from Texas Instruments, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCCA | power_in | A-side supply voltage with operating range 0.9 V to 5.5 V. |
| 2 | SCLA | bidirectional | Serial clock bus on A side, open-drain I2C line requiring external pullup resistor to VCCA. |
| 3 | SDAA | bidirectional | Serial data bus on A side, open-drain I2C line requiring external pullup resistor to VCCA. |
| 4 | GND | power_in | Supply ground connection. |
| 5 | EN | input | Active-high repeater enable input with internal pullup to VCCB. |
| 6 | SDAB | bidirectional | Serial data bus on B side, open-drain I2C line requiring external pullup resistor to VCCB. |
| 7 | SCLB | bidirectional | Serial clock bus on B side, open-drain I2C line requiring external pullup resistor to VCCB. |
| 8 | VCCB | power_in | B-side and device supply voltage with operating range 2.7 V to 5.5 V. |
