No interrupt — plan for polling
This expander does not include an interrupt output. The host must poll the device over SPI to detect input changes.
No end-of-life notice or last-time-buy risk for current designs.

Frequently asked questions
Does MAX7317AEE+T have an interrupt output?
No, this part does not include an interrupt output. Input changes must be detected by polling over the SPI interface.
What is a direct replacement or equivalent for MAX7317AEE+T?
Within the same family, the MAX7317AEE+ (without the T suffix) is the same die in a different packing option. For a pin-compatible alternative with an interrupt output, check the MAX7318 series — same footprint, adds an INT pin.
