Part Number: TCA9803 Tool/software: Hi TI
We replaced our DUT’s PCA9617 to TI TCA9803. (Side A 1.8V/ Side B 3.3V)
We followed the spec to NC the side B pull up resistor.
The VOL is better for TCA9803 obviously.
(see TCA9803_PIC1.png)
But when we…
Part Number: TCA9803 Tool/software: Hi,
I have a question ragarding series connection of multiple buffers.
My idea is to connect one buffer in between each slave of the i2c bus, in order to exploit the buffer function and interrupt the bus line in special…
Part Number: TCA9803 Other Parts Discussed in Thread: TXS0104E Hi,
I am developing a test daughter card, in which I2C interface from the evaluation board is used for connecting to four slave devices. In the evaluation board TXS0104 voltage level translator…
Part Number: TCA9803 HI Team,
I would like to ask a question of configuration. Is it possible the connection configuration as shown below?
Best Regards,
Part Number: TCA9803 Is there a white paper or other resource that discusses using the TCA980x with other vendor I2C buffers like the LTC4300? Our scenario is a Single Board Computer in a VPX rack uses the LTC4300A-1, and we are considering using the…

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?

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.
Regards,
