The MAX7327, a 2-wire serial-interfaced peripheral,

12 push-pull outputs and four configurable open-drain I/O ports with selectable internal pullups and transition detection. Ports are overvoltage protected to +6V, independent of supply voltage. The four I/O ports configured as inputs are continuously monitored for state changes (transition detection). State changes are indicated by the open-drain, +6V-tolerant INT output. The interrupt is latched, detecting transient changes. When the MAX7327 is subsequently accessed through the serial interface.
