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 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, 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.
