The interrupt output lets the host MCU sleep until an input changes, saving power in battery-operated designs. Together, these features can eliminate a dedicated PWM generator and reduce the MCU's polling overhead, simplifying firmware and lowering the component count. ## Package and footprint The MAX7313AEG+T is supplied in a 24-pin QSOP package with a 0.154-inch body width and 3.90 mm width. The QSOP footprint is smaller than a standard SOIC-24, saving board area in dense layouts. The part is surface-mount and available in Tape & Reel or Cut Tape — the Tape & Reel option is suited for automated pick-and-place assembly, while Cut Tape works for prototyping and low-volume builds. ## Lifecycle and sourcing reality The MAX7313AEG+T carries an Active lifecycle status and is ROHS3 compliant.","metaTitle":"MAX7313AEG+T I²C/SMBus GPIO Expander, 16 I/O, PWM, 400kHz","metaDescription":"MAX7313AEG+T 16-bit I/O expander with PWM, I²C/SMBus interface, open-drain outputs, interrupt output, 2V-3.6V supply, -40°C to +125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"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":"16","Package / Case":"24-SSOP (0.154\\\", 3.90mm 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":"24-QSOP","Current - Output Source/Sink":"50mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.53","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.53000","currency":"USD"},{"qty":10,"price":"$5.86500","currency":"USD"},{"qty":25,"price":"$5.54480","currency":"USD"},{"qty":100,"price":"$4.80560","currency":"USD"},{"qty":250,"price":"$4.55912","currency":"USD"},{"qty":500,"price":"$4.09090","currency":"USD"},{"qty":1000,"price":"$3.45016","currency":"USD"},{"qty":2500,"price":"$3.27765","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX7313.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX7313AEG+T support interrupt output?","answer":"Yes, the MAX7313AEG+T includes a programmable interrupt output that asserts when any input changes state, allowing the host MCU to avoid continuous polling."},{"question":"Does MAX7313AEG+T support both I²C and SMBus?","answer":"Yes, the interface is compatible with both I²C and SMBus, operating at a clock frequency of 400 kHz."},{"question":"Can MAX7313AEG+T replace PCA9535?","answer":"Both parts are 16-bit I²C GPIO expanders, but the MAX7313AEG+T adds PWM on each output and a wider temperature range.
