Compatibility with MAX6965, MAX7315,
and MAX7316
The MAX7320 is subset pin compatible with the
MAX6965, MAX7315, and MAX7316. The pin differ-
ences are shown in Table 4. The MAX7320 is not soft-
ware compatible with MAX6965, MAX7315, or
MAX7316. In many cases it is possible to design a PC
board to work with all these port expanders, providing
design flexibility.
