MAX7324
EVALUATION KIT AVAILABLE
I2C Port Expander with Eight Push-Pull Outputs and Eight Inputs
General Description
The MAX7324 2-wire serial-interfaced peripheral features 16 I/O ports that are divided into eight push-pull outputs and eight inputs. Each input features selectable internal pullups, overvoltage protection to +6V, and transition detection with an interrupt output.
All input ports are continuously monitored for state changes (transition detection). The interrupt is latched, allowing detection of transient changes. Any combination of inputs can be selected using the interrupt mask to assert the INT output. When the MAX7324 is subsequently accessed through the serial interface, any pending interrupt is cleared.
