macros

Table 1 lists the internal and external buffer macros used in the TFB2022AI design. To use this table, find the

pin of interest and note the macro name(s). If there is an entry only in the input macro column, the pin is an input.

If there is an entry only in the output macro column, the pin is an output. If there is an entry in both columns,

this is a 3-state bidirectional pin. The macro(s) are also listed in the electrical characteristics table.
