Hi,
For the TCA9803, I 've the below two queries:
Query 1) Apart from 400kHz, can I use 100kHz and 50kHz also.
If yes, what should be the pull up resistor value for 400k, 100k and 50k frequencies.
Query 2) As per the datasheet, section 10.2.1.2 and Figure 21 suggest selecting the TCA980x series IC based on the rise time. In the datasheet, nothing is mentioned about the pull up selection.
Kindly guide me on the pull up to be used on input side.
My requirement is:
PCB Trace Length = 35cm
Four ICs connected to the TCA9803 output
What can be the pull up resistor for 400k, 100k and 50k in this case?
can you please answer to these queries.
