It operates at a clock frequency of 400 kHz, making it suitable for moderate-speed control and status monitoring tasks in embedded systems. Each of the 16 I/O pins can be individually configured as input or output, with push-pull outputs capable of sourcing 31 mA and sinking 43 mA per pin. This drive strength is enough to directly switch small loads like LEDs or signal relays without external buffers. ## Package and board-fit for reflow assembly Housed in a 24-TSSOP package with a 4.40 mm body width and 0.65 mm lead pitch, the MAX7311AUG+T fits a standard surface-mount footprint. The supplier device package is also 24-TSSOP, so the land pattern is consistent across sourcing variants. ## Interrupt output for event-driven polling An interrupt output (INT) is provided, which asserts when any input pin changes state. This allows the host microcontroller to avoid continuous I2C polling and instead respond only when a transition is detected, reducing bus traffic and firmware overhead in systems with infrequent input events.","metaTitle":"MAX7311AUG+T I2C I/O Expander, 16-Bit, 24-TSSOP","metaDescription":"MAX7311AUG+T 16-bit I2C/SMBus I/O expander from Analog Devices. 400 kHz, 2V-5.5V supply, -40°C to +125°C.
