Each I/O is open-drain rated for 50 mA source/sink, enough to drive indicator LEDs directly without a transistor buffer. An integrated PWM generator on every output allows dimming or analog-style control — useful for panel backlights or status indicators where a separate PWM controller would add cost and board space. The interrupt output signals the host on input transitions, so the MCU doesn't have to poll the expander. That saves bus bandwidth and keeps the system in a low-power sleep state until a button press or sensor edge wakes it. ## Package and footprint Housed in a 16-TSSOP (4.40 mm wide body), the MAX7315AUE+T fits on compact PCBs where a larger SOIC or SSOP would crowd adjacent traces. Cut Tape (CT) is also available for prototyping or low-volume builds. ## Lifecycle and compliance The MAX7315AUE+T is listed as Active in production and is RoHS3 compliant. No end-of-life notice or last-time-buy window is on record. For current pricing and lead time, the part is sourced to order through independent distribution — availability and price are confirmed at quote time against an RFQ.","metaTitle":"Maxim MAX7315AUE+T I²C/SMBus GPIO Expander, 8 I/O, 400 kHz","metaDescription":"Maxim Integrated MAX7315AUE+T I²C/SMBus GPIO expander, 8 I/O, 400 kHz clock, PWM outputs, 50 mA source/sink, 2V-3.6V supply, -40°C to 125°C, 16-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"PWM","Interface":"I²C, SMBus","Output Type":"Open Drain","Mounting Type":"Surface Mount","Number of I/O":"8","Package / Case":"16-TSSOP (0.173\\\", 4.40mm Width)","Clock Frequency":"400 kHz","lifecycle_stage":"eol_hot","Interrupt Output":"Yes","Voltage - Supply":"2V ~ 3.6V","Operating Temperature":"-40°C ~ 125°C","Supplier Device Package":"16-TSSOP","Current - Output Source/Sink":"50mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.58","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.58000","currency":"USD"},{"qty":10,"price":"$4.11000","currency":"USD"},{"qty":25,"price":"$3.88600","currency":"USD"},{"qty":100,"price":"$3.36780","currency":"USD"},{"qty":250,"price":"$3.19512","currency":"USD"},{"qty":500,"price":"$2.86698","currency":"USD"},{"qty":1000,"price":"$2.41794","currency":"USD"},{"qty":2500,"price":"$2.29704","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/85329149feac9c4f4646c3362defc40b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX7315AUE+T RoHS compliant?","answer":"Yes, the MAX7315AUE+T is RoHS3 compliant."},{"question":"Can MAX7315AUE+T drive LEDs directly?","answer":"Yes.
