NAME FUNCTION
1 15 BLINK Input Port. Configurable as blink control or general-purpose input.
2 16 RST
Reset Input. Active low clears the 2-wire interface and puts the device in same
condition as power-up reset.
3 1 AD0
Address Input. Sets device slave address. Connect to either GND, V+, SCL, or
SDA to give 4 logic combinations. See Table 1.
4–7, 9–13 2–5, 7–11 O0–O8 Output Ports. O0–O8 are open-drain outputs rated at 7V, 50mA.
