TCA9617ADGKR 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 input, operating range 0.8V to 5.5V. |
| 2 | SCLA | bidirectional | Open-drain I2C SCL line on A side; requires external pull-up resistor to VCCA. |
| 3 | SDAA | bidirectional | Open-drain I2C SDA line on A side; requires external pull-up resistor to VCCA. |
| 4 | GND | power_in | Supply ground and common reference voltage. |
| 5 | EN | input | Active-high repeater enable input with internal weak pull-up resistor to VCCB; must change state only during bus idle. |
| 6 | SDAB | bidirectional | Open-drain I2C SDA line on B side; requires external pull-up resistor to VCCB. |
| 7 | SCLB | bidirectional | Open-drain I2C SCL line on B side; requires external pull-up resistor to VCCB. |
| 8 | VCCB | power_in | B-side logic supply and device operating voltage, range 2.2V to 5.5V; must power up before VCCA. |
