MAX7313 - 16-Port I/O Expander

General Description

The MAX7313 I 2 C™-compatible serial interfaced peripheral provides microprocessors with 16 I/O ports.

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

Each I/O port can be individually configured as either an open-drain current-sinking output rated at 50mA and 5.5V, or a logic input with transition detection. A 17th port can be used for transition detection interrupt, or as a general-purpose output. The outputs are capable of driving LEDs, or providing logic outputs with external resistive pullup up to 5.5V. PWM current drive is integrated with 8 bits of control.
