IS31IO7328 - ISSI

IS31IO7328 MULTI-FUNCTION I/O DRIVER

The IS31IO7328 2-wire serial-interfaced peripheral features 8 I/O ports. Ports are divided into four push pull I/Os and four open-drain I/Os and transition detection. Any of the 8 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 indi.

Features

8 I/O ports. Ports are divided into four push pull I/Os and four open-drain I/Os and transition detection. Any of the 8 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 IS31IO7328 is subsequently read through the serial interface, any pending interrupt is cleared. The open-drain outputs are rated to sink 20mA at 0.22V headroom, and are capable of driving LEDs. The R.
