Frequently asked questions
Is MAX7310ATE+T available via RFQ confirmation?
Stock levels change daily. Submit an RFQ for current availability and a firm lead time.
Does MAX7310ATE+T support both 3.3V and 5V?
Yes, the supply range of 2.3V to 5.5V covers both 3.3V and 5V logic domains without a level shifter.
Does MAX7310ATE+T have an interrupt output?
No, the MAX7310ATE+T does not have an interrupt output. If you need interrupt-on-change, look at the MAX7311 which adds that feature.
What is the difference between MAX7310 and MAX7311?
The MAX7311 adds an interrupt output and has a different I²C address map. The MAX7310 lacks the interrupt pin, so if you need edge-triggered notification from the expander, the MAX7311 is the part to cross-shop.
