Note: Due to open drain configuration of SDA, a bus-level pull-up resistor is called for, (typical value = 4.7kΩ)

Example of 16K of Memory on 2-Wire Bus

Note:

The SDA pull-up resistor is required due to the open-drain/open collector output of IIC bus devices.

The SCL pull-up resistor is recommended because of the normal SCL line inactive 'high' state.

It is recommended that the total line capacitance be less than 400pF
