Dear Team,
My customer uses the TCA9546A (4-Channel I2C and SMBus Switch). When they do not use all 4-channel, how should they handle unused serial data and clock pins (SDx, SCx). Is it OK to leave unused pins open, unused pins should be connected to VDPUx through a pull-up resistor, or thoese should be connected to GND?
I look forward to your reply.
Thank you.
Best Regads,
Koshi Ninomiya
