Product details

28-channel I²C GPIO expander for board-level signal fan-out

The MAX7300ATL+ is a 28-bit GPIO expander with an I²C interface running at 400 kHz, designed to add digital I/O to a microcontroller or SoC without dedicating processor pins.

Temperature grade and package fit for industrial boards

Supplied in tube format, which is the standard delivery for prototype and low-volume builds; for reel quantities the order code differs.
