MAX7313AEG+T

MAX7313AEG+T is Maxim Integrated’s I2C-controlled 16‑bit I/O expander/LED driver. It lets a microcontroller extend its I/O footprint over the I2C bus, providing 16 GPIO that can be configured as inputs or outputs (and used to drive LEDs or logic signals). Key features typically include an I2C interface (SMBus-compatible), configurable direction and polarity, optional pull-ups, an interrupt output, and a RoHS-compliant packaging with Tape & Reel (the AEG+T suffix). Supply range is usually in the 2.7–5.5 V region, with outputs capable of sinking/sourcing limited current suitable for simple LED driving and logic. Applications include expanding MCU I/O, LED driving, and general-purpose GPIO expansion in embedded systems. For exact pinout, electrical characteristics, and package details, consult the latest MAX7313 datasheet.
