TCA9803DGKT from Texas Instruments, in a VSSOP-8-0.65mm. 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, 0.8 V to 3.6 V |
| 2 | SCLA | bidirectional | Serial clock bus, A-side; connect to VCCA through pull-up resistor, even if unused |
| 3 | SDAA | bidirectional | Serial data bus, A-side; connect to VCCA through pull-up resistor, even if unused |
| 4 | GND | power_in | Ground |
| 5 | EN | input | Active-high repeater enable input, referenced to VCCA |
| 6 | SDAB | bidirectional | Serial data bus, B-side; do not connect to VCCB through pull-up resistor for proper operation, if unused leave floating |
| 7 | SCLB | bidirectional | Serial clock bus, B-side; do not connect to VCCB through pull-up resistor for proper operation, if unused leave floating |
| 8 | VCCB | power_in | B-side and device supply voltage, 1.65 V to 3.6 V |
