MAX7313 16-Port I/O Expander with LED Intensity Control, Interrupt, and Hot-Insertion Protection

16-Port I/O Expander with LED Intensity Control, Interrupt, and Hot-Insertion Protection. The MAX7313 I²C-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. 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.
