SN7325 - Multi Function I/O Driver

Download the SN7325 datasheet PDF. This datasheet also covers the SN7325_Si variant, as both devices belong to the same multi function i/o driver family and are provided as variant models within a single manufacturer datasheet.

Description

The SN7325 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 SN7325 is subsequently read through the serial interface, any pending interrupt is cleared. The.

SN7325 www.DataSheet4U.com Multi-function I/O Drive General Description The SN7325 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 SN7325 is subsequently read through the serial interface, any pending interrupt is cleared. The open-drain outputs are rated to sink 20mA at 0.26V headroom, and are capable of driving LEDs.
