TI中文支持网Part Number:TCA9548AOther Parts Discussed in Thread: TPS22993
I have used 8 pieces TCA9548A and 8 pieces TPS22993 by one I2C in one Printed Circuit Board Assembly.
I have a question. TCA9548A I2C address and TPS22993 I2C address are conflicted. Do you have solution to use 8 pieces TCA9548A and 8 pieces TPS22993 by one I2C bus ?
TPS22993 I2C address are as follows
E0/E1 = 1110 000x, x = A0 = 1 or 0
E2/E3 = 1110 001x, x = A0 = 1 or 0
E4/E5 = 1110 010x, x = A0 = 1 or 0
………
TCA9548A I2C address are as follows
1110 000x
1110 001x
1110 010x
……..
It seems that the I2C address are conflicted. 8 pieces TCA9548A and 8 pieces TPS22993 by one I2C can NOT be used simultaneously.
Do you have any solution, except two I2C bus is used ?
I want to find a local technical support engineer. I want a office phone, and Email to talk to him/her directly.

您好，
TCA9548A是I2C扩展设备，您可以级联2片TCA9548A，这样可以连接更多的I2C slave，下面两个帖子说明了一些注意事项：
