failures.
8.1 Short Pin Descriptions
Table 8-1. DS3184 Short Pin Descriptions
n = 1,2,3,4 (port number). Ipu (input with pullup), Oz (output tri-stateable), (needs an external pullup or pulldown resistor to keep from floating),
Oa (analog output), Ia (analog input), IO (bidirectional in/out). All unused input pins without pullup should be tied low.
