IS31IO7325 MULTI-FUNCTION I/O DRIVER August 2012 GENERAL DESCRIPTION The IS31IO7325 2-wire serial-interfaced peripheral features 16 I/O ports.
Ports are divided into eight push pull I/Os and eight open-drain I/Os and transition detection.
Any of the 16 I/O ports can be configured as an input or an output.
All I/O ports configured as inputs are continuously monitored for state changes (transition detection).
State changes are indicated by the INT output.
The interrupt is latched, allowing detection of transient changes.
When the IS31IO7325 is subsequently read through the serial interface, any pending interrupt is cleared.
The open-drain outputs are rated to sink 20mA at 0.
