The I²C/SMBus interface runs at 400 kHz (Fast Mode), compatible with most MCU I²C peripherals. The bus address is set by three hardware pins, allowing up to eight devices on the same bus for a total of 128 I/O lines. A dedicated interrupt output (IRQ) asserts when any input changes state, eliminating the need for the host to poll the port. In battery-powered designs, this lets the MCU sleep until a button press or sensor edge wakes it, reducing average current draw. ## Power-on reset and default state The POR (Power-On Reset) feature ensures all I/O pins power up as inputs in a high-impedance state. This prevents uncontrolled output glitches during supply ramp — critical when the expander shares a rail with a watchdog or safety-critical actuator. Supplied in tube packaging — 24-SOIC tubes typically hold 30–40 units per tube. For reel or tape-and-reel requirements, confirm the alternate order code (MAX7311AWG+T) with your sourcing contact.","metaTitle":"MAX7311AWG+ I²C/SMBus I/O Expander, 16 I/O, 24-SOIC","metaDescription":"MAX7311AWG+ 16-bit I/O expander with I²C/SMBus interface, 400 kHz clock, 2V-5.5V supply, -40°C to +125°C.

A direct pin-compatible alternative within the same family is the MAX7311ATG+ in a 24-TQFN package — note the different footprint requires a board layout change.
