SCPS267B March 2017 – February 2020 TCA9803
The system designer must first select the correct variant of the TCA980x family for the load. In order to do this, the information in Table 7 must be known. The setup in Figure 29 is used for these example design requirements.

|CL||Load capacitance (bus capacitance) on B-side||up to 400 pF||200 pF|
|tr||Rise time||up to 300 ns||≤ 300 ns|
|VCCA||VCCA supply voltage||0.8 V-3.6 V||2.5 V|
|VCCB||VCCB supply voltage||1.65 V-3.6 V||2.5 V|
|fSCL||I2C clock frequency||400 kHz|
