Dear Derek -
One solution would be to use an I2C mux, which could be designed with this simple 2 channel device, which would allow you to put up to four TMP117s on one channel, and the remaining on the second channel: https://www.ti.com/product/TCA9543A…
Other Parts Discussed in Thread: TCA9543A , TMUX1072 Hi,
I am currently considering using the TCA9543A, but this chip requires I2C commands to select between Channel 0 and Channel 1. I and looking for an equivalent mux/switch that can select between…
Hi Evan,
Could you see if the TCA9543A can be used in your application? I would note that this device is capable of operation up to 400KHz however.
Regards,
Jack

I'd like to confirm this, can TCA9534A support 1.8V as input, 3.3V as output application?
Thanks.

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…
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…
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…
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…
