The latch holds the comparison result on the TTL output until the latch-enable signal resets it, making this part suited for sampled-data systems — zero-crossing detectors, window comparators, and overcurrent trip circuits where the decision must be held for a controller read cycle. The wide supply range (4.75 V to 10.5 V single, or ±2.375 V to ±5.75 V dual) lets it drop into existing 5 V or ±5 V rails without a local regulator. With 86.02 dB typical CMRR and PSRR, it rejects supply ripple and common-mode noise common in motor-drive and industrial-control backplanes. ## Industrial temperature rating — deployment context Rated for -40°C to 85°C, this comparator handles outdoor telecom cabinets, factory-floor sensor interfaces, and engine-bay electronics without derating. The SOT-23-8 footprint keeps board area small, but the thermal path is through the leads — ensure adequate copper on the pads for heat spreading if the part is near a hot regulator or power stage. ## Quiescent current and input bias — what they mean for the BOM Maximum quiescent current is 2 mA (with lower bins at 1.6 mA and 800 µA), so the part adds negligible load to a 5 V or ±5 V rail — fine for battery-backed or low-power supervisory circuits. Input bias current maxes at 5 µA at ±5 V, and input offset voltage at 4 mV at ±5 V. These are typical for a general-purpose comparator; for precision threshold detection below a few millivolts, you would need a zero-drift or chopper-stabilised alternative. ## Lifecycle and compliance The MAX9203EKA+T carries an Active lifecycle status and is ROHS3 compliant.","metaTitle":"MAX9203EKA+T Comparator with Latch, SOT-23-8, -40°C to 85°C","metaDescription":"MAX9203EKA+T single comparator with latch output, TTL, 86.02 dB CMRR/PSRR, 4.75V to 10.5V supply, SOT-23-8, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"with Latch","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"TTL","Mounting Type":"Surface Mount","Package / Case":"SOT-23-8","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"86.02dB CMRR, 86.02dB PSRR","Number of Elements":"1","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"SOT-23-8","Current - Quiescent (Max)":"2mA, 1.6mA, 800µA","Current - Input Bias (Max)":"5µA @ ±5V","Voltage - Input Offset (Max)":"4mV @ ±5V","Voltage - Supply, Single/Dual (±)":"4.75V ~ 10.5V, ±2.375V ~ 5.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.28","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.28000","currency":"USD"},{"qty":10,"price":"$3.84600","currency":"USD"},{"qty":25,"price":"$3.63600","currency":"USD"},{"qty":100,"price":"$3.15120","currency":"USD"},{"qty":250,"price":"$2.98960","currency":"USD"},{"qty":500,"price":"$2.68256","currency":"USD"},{"qty":1000,"price":"$2.26240","currency":"USD"},{"qty":2500,"price":"$2.14928","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/44c8c181424efea8b8b815d64883072d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX9203EKA+T have a latch output?","answer":"Yes, the MAX9203EKA+T is a comparator with latch, meaning the TTL output holds the comparison result until the latch is reset — useful for sampled or held-decision circuits."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX9203EKAT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX9203EKAT when reusing this data.
