MAX xxxx 8 Yes MAX xxxx 8 MAX xxxx Up to 8 Up to 8 MAX xxxx 4 Yes 4 Offers maximum versatility for automatic input monitoring. An interrupt mask selects which inputs cause an interrupt on transitions, and transition flags identify which inputs have changed (even momentarily) since the ports were last read. Output-only versions: 8 push-pull outputs with selectable power-up default levels. Push-pull outputs offer faster rise time than opendrain outputs, and require no pullup resistors. I/O versions: 8 open-drain I/O ports with latching transition detection interrupt and selectable pullups. Open-drain outputs can level shift the logic-high state to a higher or lower voltage than V+ using external pullup resistors. Any port can be used as an input by setting the open-drain output to logic-high. Transition flags identify which inputs have changed (even momentarily) since the ports were last read. 4 input-only, 4 output-only versions: 4 input ports with programmable latching transition detection interrupt and selectable pullups; 4 push-pull outputs with selectable power-up default levels. 5
