It adds 20 push-pull GPIO lines to a host MCU that may be short on pins, without consuming additional address space — the slave address is set by three hardware pins, so up to eight devices share the same bus segment. Each I/O can source 4.5 mA or sink 10 mA, enough to drive LEDs directly or interface to logic inputs without a buffer. An interrupt output signals the host when an input changes, eliminating the need for continuous polling over I2C. ## 28-SSOP package and board integration Housed in a 28-SSOP (0.209-inch body width, 5.30 mm), the MAX7300AAI+ uses a standard 0.65 mm pitch footprint. The supplier device package is 28-SSOP, so the land pattern matches the common SSOP-28 library part. Tube packaging means the parts ship in anti-static tubes — store the reels dry if the tube is opened and the ambient humidity is above the MSL rating. ## Active lifecycle and compliance ROHS3 compliant, so it meets the EU RoHS directive without exemption.","metaTitle":"MAX7300AAI+ I2C Port Expander, 20 I/O, 28-SSOP","metaDescription":"MAX7300AAI+ I2C port expander from Analog Devices. 20 GPIO, 400 kHz I2C, 2.5V–5.5V supply, -40°C to 125°C.
