Part Number: P82B715 Other Parts Discussed in Thread: TCA9543A Dear team,
My customer is looking for a solution to communicate with the sensor board that is 2 meters away from the main board.
Firstly, I recommended to use P82B715 but the customer…
Part Number: TCA9546A Other Parts Discussed in Thread: TCA9543A , PCA9306 Hi there,
My customer is now using TCA9546A in one of their projects. However, they're complaining that the size is too big.
Since they only need two channels, I found TCA9543A…
Hi Kay,
I think you should only need one TCA9543A near the master (or at a junction point between the two sensor boards), though two would work as well.
I have no expertise with the TCA9543A, but looking at the datasheet I would suspect that if you…
Hey Minglai,
PCA9543A should be high impedance (or open as you call it) on SDA/SCL if no channels are enabled (selected) when it is turned on. Please ensure though you meet the Vcc ramp requirement specified in section 11 of the datasheet though because…

Marco,
TCA9543A (link below) is quite similar to the NXP PCA9541A, as it is a 2 to 1 I2C master selector.

Our TCA9543A has a much lower supply voltage (1.65 V to 5.5 V) and has corrected the errata from our previous…
Hey Derek,
I currently set an order to be shipped to me for the PCA9543A and TCA9543A to confirm whether or not bits 7 and 2 can be writable or if they are forced to be 0's even after a write occurs. I expect to receive the samples and be ready to…
