The 16 I/O lines are configured as push-pull outputs, meaning each pin can source 31 mA or sink 43 mA — enough to drive an LED directly or switch a small relay without an external transistor. The I2C bus runs at 400 kHz, which is the standard fast-mode speed. For reading or writing 16 bits of data, the bus transaction takes roughly 50 µs, so the expander is well suited for status polling or setting outputs at a control-loop rate of a few kilohertz. The interrupt output lets the expander signal the host only when an input changes, avoiding constant polling and saving bus bandwidth. ## Power-on reset and supply flexibility The POR (power-on reset) feature ensures that all I/O pins default to a known high-impedance state at power-up, so external loads are not driven until the host configures the expander. This is critical in systems where an output could accidentally energize a load during startup. The wide range also allows the expander to run on a battery that droops below 3 V without needing a separate regulator. The supplier device package is 24-TSSOP, and the part is available in Tape & Reel (TR) or Cut Tape (CT) for pick-and-place assembly.","metaTitle":"MAX7312AUG+T I2C Port Expander, 16 I/O, 24-TSSOP","metaDescription":"MAX7312AUG+T I2C/SMBus 16-bit GPIO expander with POR, 400 kHz, push-pull outputs, 31mA/43mA drive, -40°C to +125°C, 24-TSSOP.
