TXS0102: About TXS0102 A port and B port I2C Parasitic capacitance

James Zhang6

Part Number: TXS0102

Hi TI

I have question about TXS0102's A port and B port I2C parasitic capacitance.

I useTXS0102 to separate two kind level voltage but I worry the I2C bus is very length.

How to calculate the I2C bus parasitic capacitance when uses TXS0102 IC?

Best regards

James

The I/O capactiance is specified in section 6.5 of the datasheet. That 10 pF probably does not matter.

If you are concerned about the bus capacitance, consider using some active I²C buffer, e.g., TCA980x.
