Part Number: TCA9803 Other Parts Discussed in Thread: P82B96 Tool/software: Hi,
Custiomer now have a cable product application, and the transmission distance on the I2C bus needs to be larger than 7m. They want to use TCA9803 on the host pcb and the…
Part Number: TCA9803
Tool/software:
Hello,
In TCA9803 datasheet, VOL (Low-level output voltage) is only specified when the input is 0V:
-> Low-level output voltage (VOL) of SDAA and SCLA are specified for VILB =0V.
-> Low-level output voltage (VOL…
Sylvain,
According to the other thread, testing ICCQ may not be needed if we cannot get TCA9803 to work in your system.
I will put this thread on pause for now.

Tyler
Part Number: TCA9803 Tool/software: Hi team,
My customer is using TCA9803, and wondering what is the impedance value when A side is power off? Could you pls share the impedance value in this case? Thank you!
Powered-off high impedance I 2C bus pins on…
Part Number: TCA9803 Tool/software: Hello.
Please be so kind and help to review customer schematic using TCA9803 provide your feedback and eventually any proposal if you have any.
If the resolution is not good let me know I can send it over email.
Thank…
Part Number: P82B96 Other Parts Discussed in Thread: TCA9803 , Tool/software: Hi support team,
As shown in the figure, when I connected the TCA9803 to PB2B96 in order to reduce the output voltage (VOL), I observed that the falling time of the SDA signal…
Part Number: TCA9803 Tool/software: Hi team,
I would have a question regarding the TCA9803. Would it be possible to use this device as a buffer for 1.8V, but also to change the input impedance from example 2.2k Ohm at the input to 100k Ohm at the output…
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…
