LSF0204-Q1: Pull-Up resistor value

Kurumi Hasegawa

Part Number: LSF0204-Q1

Hi team,

I've got question from the customer and I'd like to ask your help.

Would it be OK to use pull-up resistors on the A-side larger than the recommended one on the table 4?

For example, with 3.3V Vdpu,1k ohm is recommended to limit the current 3mA. Is it OK to use 10k ohm instead? How about 100k ohm? Would it cause any trouble?

Regards,

These recommendations tell you what resistors are needed if you want to achieve certain currents. If you do not need that much current (because you circuit's capacitance is very low, or because you do not need high speeds), then you can use larger resistors.
