Overview

com 19-3805; Rev 0; 8/06 I2C Port Expander with 12 Push-Pull Outputs and 4 Open-Drain I/Os General Description The MAX7327, a 2-wire serial-interfaced peripheral, features 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, any pend...
