Eight-port I²C expander for industrial and automotive I/O
The Maxim Integrated MAX7320ATE+ is an 8-bit I²C GPIO expander that provides eight configurable I/O ports with open-drain or push-pull output selection.
Output drive and port configuration
Each of the eight I/Os can sink or source up to 25 mA, allowing direct drive of LEDs, small relays, or logic-level loads without external buffers. The output type is selectable per port between open-drain and push-pull, giving flexibility for wired-OR connections or standard digital outputs. No interrupt output is provided, so the host must poll the expander over I²C to detect input changes.
Package and footprint details
For current designs, this part presents no near-term obsolescence risk.
