MAX7320 Maxim, MAX7320 Datasheet - Page 12

• Manufacturer Part Number: MAX7320
• Description: The MAX7320 2-wire serial-interfaced peripheral features eight push-pull outputs with selectable power-up logic states
• Manufacturer: Maxim

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.
