Maxim Integrated MAX7314 18-Port GPIO LED Intensity Control & Interrupt Datasheet
The MAX7314 is an I²C‑compatible 18‑port GPIO peripheral that provides 16 configurable I/O ports plus one output‑only port that can serve as an interrupt. Each port can be set as an open‑drain output (up to 50 mA) or a logic input with transition detection, and includes per‑port PWM LED intensity control and two‑phase blinking.
The device operates from a 2 V to 3.6 V supply, supports hot‑insertion, and is offered in a thin 4 mm × 4 mm QFN package. Typical applications include LCD backlights, LED status indicators, relay drivers, keypad backlights, and RGB LED drivers.
