TPT72617-SO1R

3PEAK · I2C Isolators · SOIC-8

TPT72617-SO1R from 3PEAK, in a SOIC-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 Side A power supply; the recommended operating range for VCCA is 3 V to 5.5 V (page 5), and the device is non-functional below 2.1 V (page 18).
2 SDAA bidirectional Side A serial data input/output of the open-drain I2C bus, with a recommended sink current of 0.5 mA to 3.5 mA (page 5).
3 SCLA bidirectional Side A serial clock input/output of the open-drain I2C bus, with a recommended sink current of 0.5 mA to 3.5 mA (page 5); on the TPT72617 this channel is bidirectional.
4 GNDA power_in Ground connection for the side A supply VCCA.
5 GNDB power_in Ground connection for the side B supply VCCB.
6 SCLB bidirectional Side B serial clock input/output of the open-drain I2C bus, with a recommended sink current of 0.5 mA to 35 mA (page 5).
7 SDAB bidirectional Side B serial data input/output of the open-drain I2C bus, with a recommended sink current of 0.5 mA to 35 mA (page 5).
8 VCCB power_in Side B power supply; the recommended operating range for VCCB is 3 V to 5.5 V (page 5), and the device is non-functional below 2.1 V (page 18).
