The SOT-143-4 surface-mount package keeps the footprint small. ## Active production and sourcing reality The MAX821TUS carries an active lifecycle status from Maxim Integrated, so there is no end-of-life risk for current production runs or new designs. It is RoHS non-compliant, which matters for EU markets or any BOM with a RoHS-only mandate — verify your assembly's exemption or plan for a lead-free alternative if needed.","metaTitle":"MAX821TUS Simple Reset/Power-On Reset, 3.08V Threshold","metaDescription":"MAX821TUS is an active-low push-pull voltage monitor with 3.08V threshold, -40°C to 125°C range, in SOT-143-4.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"Adjustable/Selectable","Package / Case":"TO-253-4, TO-253AA","lifecycle_stage":"eol_hot","Voltage - Threshold":"3.08V","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-143-4","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.78","stockQuantity":0,"priceTiers":[{"qty":109,"price":"$2.78000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/053808dc63be9bb322c065c4708b6130.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the MAX821TUS reset threshold voltage?","answer":"The reset threshold is 3.08V, making it a fit for monitoring a nominal 3.3V supply rail.
