The 20 mA source/sink per pin drives a standard LED directly or switches a small-signal MOSFET gate through a series resistor. ## Lifecycle and compliance The MAX7322ATE+T is listed as Active with ROHS3 compliance. The Tape & Reel (TR) and Cut Tape (CT) packaging options suit both volume production and prototype runs.","metaTitle":"MAX7322ATE+T I²C Port Expander, 4 I/O, 400 kHz, 16-TQFN","metaDescription":"MAX7322ATE+T I²C port expander with 4 I/O, 400 kHz clock, 1.7V–5.5V supply, -40°C to 125°C range.

They are not pin-compatible; the MAX7322 has a different I²C address map and fewer I/O. For a direct 4-port replacement with interrupt, the MAX7322 is the correct part."},{"question":"What is the I²C address of MAX7322ATE+T?","answer":"The MAX7322 uses a fixed I²C slave address determined by the AD0 and AD1 pin strapping. Refer to the datasheet for the address table; the base address is 0x60 (7-bit) with two programmable bits via the address pins, giving four possible addresses."},{"question":"What is the difference between MAX7322 and MAX7323?","answer":"The MAX7322 provides 4 I/O ports with interrupt output; the MAX7323 provides 8 I/O ports also with interrupt output. Both use the same 16-TQFN package and I²C interface, but the MAX7323 requires a different I²C address and has twice the GPIO count."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX7322ATET","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX7322ATET when reusing this data.
