8 PIN DESCRIPTIONS
Note: In JTAG mode, all digital pins are bidirectional to increase the effectiveness of board level ATPG patterns for
isolation of interconnect failures.
8.1 Short Pin Descriptions
Table 8-1. DS3174 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 inout); all unused input pins without pullup should be tied low.
