max7314atg+ Description

Short technical summary and product information.

The MAX7314ATG+T is an I2C-compatible serial interfaced peripheral from Maxim Integrated, providing microprocessors with 18 I/O ports. Each port can be individually configured as an open-drain current-sinking output rated at 50mA and 5.5V, or as a logic input with transition detection. The device supports a 400kbps, 2-wire serial interface and operates from 2V to 3.6V.

 

Key features include overall 8-bit PWM LED intensity control with global and individual step adjustments, and 2-phase LED blinking. The outputs are 5.5V-rated open-drain, and inputs are overvoltage protected to 5.5V. The MAX7314ATG+T also supports hot insertion, making it suitable for applications requiring reliable system I/O.

 

This IO expander is available in a compact 4mm x 4mm Thin QFN package and operates across a temperature range of -40°C to +125°C. Its versatile features make it ideal for applications such as LCD backlights, LED status indication, relay drivers, and keypad backlights.
