  • Page 19: Pin Configuration

    PIN CONFIGURATION A ìCMOS output pinî means it can sink and drive at least 4mA current. It is not recommended to use such pin as input function. A ìopen drain pinî means it can sink at least 4mA current but only drive 10~20uA to VDD. It can be used as input or output function and needs an external pull up resistor.
