Typical System Configuration
Note:
Due to open drain configuration of SDA and SCL, a bus-level pull-up resistor is called for, (typical value = 4.7k
Ω)
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
