Other Parts Discussed in Thread: TCA9517
Hello,
If i plan to use the TCA9517 in series, to connect an I2C bus on multiple boards, is the design intent shown in figure 9 in the datasheet to use the same power source for VCCA and VCCB for all of the buffers? If i actually have different power sources, 3.3V supplies, on each board how should VCCA and VCCB be connected on each board? Should the 3.3V rail on board 1 connect to VCCA and VCCB of the first buffer and the 3.3V rail from board 2 connect to VCCA and VCCB of the second buffer.
Please note that each board does not access to the other boards 3.3V rail.
Thanks,
Brandon
