and Hot-Insertion Protection
Input Port. Configurable as blink control or general-purpose input.
Reset Input. Active low clears the 2-wire interface and puts the device in same
condition as power-up reset.
Address Input. Sets device slave address. Connect to either GND, V+, SCL, or
SDA to give 4 logic combinations. See Table 1.
Output Ports. O0–O8 are open-drain outputs rated at 7V, 50mA.
Ground. Do not sink more than 190mA into the GND pin.
