Hello community,
We have to interface 4 to 5 x TMP1075 sensors with our MCU over a maximum bus length of 5m. This…

Hello, in the figure, the 3.3V/1.8V master requires communication with four 1.2V slaves through I2C buffer. Is there any suitable scheme to recommend
Part Number: TCA9803 Hi all,
I would like to ask a question of configuration.
Is it possible the connection configuration as shown below?
Can I connect TCA9803 from BUS B in parallel?
Best Regards,

Hi,
Glad we could talk about this. I made a note in actions items for our I2C IBIS models for the team. I will talk with upper management and design teams to see what actions we can take to update the models.

Part Number: TCA9803 If the voltage of VCCB and the supply voltage of the slave side IC are the same, is it correct to use without pull-up from the figure shown in the data sheet?
Part Number: TCA9803 Hi all,
I would like to ask a question of configuration.
Is it possible the connection configuration as shown below?
Can I connect the Slave MCU and sensors between TCA9803?

Part Number: TCA9803 Hi TI team,
We are using TCA9803 as I2C buffer and it has to drive 5 slave devices. (Please see below sketch)
Will it be an issue to drive 5 slaves devices like this?
Clock used in this case would be 400kHz.
If approximate 10-13pF…
Part Number: TCA9803 Other Parts Discussed in Thread: TCA9406 Hi Team,
I need a simple voltage translator for I2C.
I was looking at the TCA9803. Side B of the device has current source that is always active. I verified the connected device leakage and…
Part Number: TCA9803 Other Parts Discussed in Thread: SN74LVC1G07 My I2C controller will directly connect to about eight I2C devices. I plan on adding TCA9803 devices with port A connected to the I2C controller side and the four level shifted/isolated…
Virtuix,
Virtuix Inc. said: Originally we tried using TVS diodes on the SDA/SCL lines, but we found that the very fast transient emanating from the slave bus (caused by hot unplugging of the bus cable on the bus master board) was damaging the TVS diodes…
