The TCA9617ADGKR is a bidirectional I2C bus repeater designed to work in various digital systems, including I2C and SMBus applications. It features a total of 8 pins. Here is a concise breakdown of its pin functions:
1. A side (SDAA, SCLA): These are the open-drain I2C bus pins on the A-side, which are connected to the lower voltage I2C bus.
2. B side (SDAB, SCLB): These are the open-drain I2C bus pins on the B-side, used for connection to a higher voltage I2C bus.
3. VCC(A): Power supply for A-side circuitry.
4. VCC(B): Power supply for B-side circuitry, which can operate at a higher voltage level than VCCA.
5. GND: Ground pin, common for both sides.
6. EN: Enable pin used to activate or deactivate the repeating function.
This device isolates capacitance and allows for level shifting between I2C buses operating at different voltages, enhancing communication reliability.
