Part Number: TCA9548A Hi
We are using part TCA9548ARGER in our new design. VCC is connected with 3.3V and Main communication lines are also at 3.3V level and pulled up with 3.3V supply. We need different Pull up supply (5V and 3.3V) at Downstream ports…
Part Number: TCA9548A Tool/software: I have 3.3V and 1.8V I2C on one side. Should I connect the chip VCC to 3.3V or 1.8V? I think it should be 3.3V, please confirm. If 3.3V, the output could be as high as 2.1V, I have to check the 1.8V chip is okay or…
Part Number: TCA9548A Tool/software: Dear team,
Good day!
Here i bought TCA9548APWR twice in different DC but COO is the same country, our QC team found that X-ray results are fifferent in lead frame as pic below, could you help clarify are they…
Part Number: TCA9548A Tool/software: Hello Have the below design, I am using a PIC18F87J50 for the I2C master, problem is that I can get clock/data on pins 22 and 23 but nothing on the other end, any suggestions of why this can be ?
Part Number: TCA9548A Tool/software: Hi team,
In our design, we're using the TCA9548APWR I²C bus switch, but we only require 7 of the 8 available channels. Should the unused channel be left floating, or would it be better to pull it up?
Regards, …
Part Number: TCA9548A Hi
I design this switch where we have 2.2K PU on O/P.
When i probe the o/p signal after giving i2cdetect command. I2C is toggling from 3.3V to 2.41V.
Now i conncted all 4 o/p PU with 10K then it is going till 0.8V and starts…
Part Number: TCA9548A Tool/software: Hi,
In one of our designs, we’re using this component to isolate the I2C paths to our slave ICs. The goal is to prevent a single I2C slave failure from disabling the entire I2C bus.
For example, if one of the slave…
Part Number: TCA9548A Tool/software: Hello,
I am using the TCA9548 to communicate with "slave" boards that are to be connected to the "master" board via up to 3 foot long cables. The master PCB has the TCA9548 connecting to slave boards using the I2C…
