TCA9801DGKR 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 with operating range 0.8 V to 3.6 V. |
| 2 | SCLA | bidirectional | I2C serial clock A-side; open-drain bidirectional requiring external pull-up resistor to VCCA. |
| 3 | SDAA | bidirectional | I2C serial data A-side; open-drain bidirectional requiring external pull-up resistor to VCCA. |
| 4 | GND | power_in | Ground reference. |
| 5 | EN | input | Active-high repeater enable input with internal pull-up resistor (150 kΩ to 450 kΩ) referenced to VCCA. |
| 6 | SDAB | bidirectional | I2C serial data B-side with 1.1 mA integrated current source; no external pull-up resistor permitted. |
| 7 | SCLB | bidirectional | I2C serial clock B-side with 1.1 mA integrated current source; no external pull-up resistor permitted. |
| 8 | VCCB | power_in | B-side supply voltage with operating range 1.65 V to 3.6 V. |
