General Description

The MAX7315 I2C™-/SMBus-compatible serial interfaced peripheral provides microprocessors with 8 I/O ports.

Each I/O port can be individually configured as either an open-drain current-sinking output rated at 50mA at 5.5V, or a logic input with transition detection.

A ninth port can be used for transition detection interrupt or as a generalpurpose output.
