The 8 input-only I/O means this part is designed for reading switch states, sensor thresholds, or digital signals — it does not drive outputs. The interrupt output (IRQ) signals the host when any input changes, eliminating continuous polling on the I2C bus. ## Supply voltage and temperature envelope The 1.71 V minimum supply lets the expander run directly off a 1.8 V logic rail, common in low-power MCUs and SoCs. The POR (power-on reset) feature ensures the I/O states are initialized to a known condition after the supply crosses the threshold, so the host reads valid levels on first I2C access. ## Package and board integration Both are surface-mount, fine-pitch packages suited for compact PCB layouts. The tube packaging is typical for prototype and low-volume builds; for reflow assembly, the part is also available in tape-and-reel from the same series.","metaTitle":"MAX7319AEE+ I2C Port Expander, 8 Inputs, 16-QSOP","metaDescription":"MAX7319AEE+ I2C port expander from Analog Devices, 8 input-only GPIO, 1.71-5.5V, -40 to 125°C, 25mA I/O, POR, interrupt output.
