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-Q1 Tool/software: can set I2C target address same as the device I2C address?
example: TCA9548 0X74,target address also set as 0X74?
Part Number: TCA9548A Tool/software: Hello,
I was using the TCA9548A and tried to do some I2C writes to it. I connected A0, A1, and A2 to GND, and the TCA9548A's address should be 0x70 according to the datasheet. However, when I tried to write to it at…
Part Number: TCA9548A Tool/software: Hi TI Team,
I saw Data hold time of I2C in datasheet is 0ns.
But i also saw the note: A device internally must provide a hold time of at least 300 ns for the SDA signal (referred to the VIH min of the SCL signal),…
Part Number: TCA9548A Tool/software: Dear TI Team:
I get information from datasheet of TCA9548 that it can support Hot insertion.
1.Could you pls explain more detail how the TCA9548 support Hot insertion?
2. In the event the slave is communicating while…
Part Number: TCA9548A
Hello,
I have a board with 2 TCA9548A chips. One with address x70 and the other with address x71.
Im using a NI USB-8452 as the I2C Master sending the data from my application.
The SCL and SDA pins have a pull up resistor of 4.7kOm…
Part Number: TCA9548A Tool/software: Hi All,
Can you help me how to calculate the I2C fall time calculations to meet the standard specifications.

Part Number: TCA9548A Please let me know how to make a statement in Python and to select correct channel. Then switch to another.
I2C address 0x70 is the default.
Now, I have 3 channels open at one time ; 0 , 4 and 7.
Thank u
Part Number: TCA9548A Tool/software: Hi All,
I am using the TCA9548AMRGER one of my application, In that out of 8 channels i am using only 3 output channels.
So rest 5 channels are unused , so please confirm the unused channels can be left open or…
Part Number: TCA9548A Tool/software: I have built a 1 to 64 I2C multiplexer/demultiplexer based on 9 TCA9548A devices: one as primairy (address 0) to split the master I2C onto 8 intermediate busses and subsequently 8 TCA9548A devices (all on address…
