TCA9803: step voltage in SDAB/SCLB falling edge

Part Number: TCA9803

Hi, team,

I have one question about TCA9803 may need your help.

Customer's application is like below. Master is NXP LS1046A CPU, Slave is EEPROM.

In testing, we found there is a 700~800mV/100ns voltage step in SDAB and SCLB falling edge as shown below. Is it caused by the device internal current source?

Thanks.

Johnny
