TI Product of Function Like NXP PCA9541A

Other Parts Discussed in Thread: TCA9543A

I would like to know if TI has similar product or solution on I2C master selector like NXP PCA9541A as I search on the web and it seems that only NXP has this type of IC.

Anybody know what is the reason or if this is a patent issue? Or if this solution is not common used?

Thanks a lot.

Marco,

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

www.ti.com/.../datasheet

Our TCA9543A has a much lower supply voltage (1.65 V to 5.5 V) and has corrected the errata from our previous PCA devices.

Let me know if this fits your solution.

Thanks,
Siby

Hi Marco,

Sorry about the delayed response, but I was mistaken in my recommendation for a multi master I2C switch. We currently DO NOT have an I2C switch that can support the functionality of the NXP PCA9541A.

Thanks,
Siby
