Each of the 16 I/O lines can be configured independently as input or push-pull output, and the part includes a power-on reset (POR) feature that initializes the outputs to a known state after power-up. The 400 kHz clock frequency supports standard and fast-mode I²C buses, and the interrupt output (INT) signals the host when an input changes state, reducing polling overhead. ## Output drive and package Each output can source 31 mA or sink 43 mA, enough to drive an LED or a small relay coil directly without a transistor buffer. The part is surface-mount only. For dual-sourcing or supply resilience, Maxim's own MAX7318 family includes the same 16-bit I²C expander in different package options; the AAG+ variant is the 24-SSOP version.","metaTitle":"MAX7318AAG+ I2C I/O Expander, 16-Bit, 400 kHz, 24-SSOP","metaDescription":"MAX7318AAG+ 16-bit I2C/SMBus I/O expander with POR, push-pull outputs, 31mA/43mA source/sink, -40°C to 125°C, 24-SSOP.
