Without it, a slowly crossing input can cause the output to oscillate, which downstream logic reads as a fault. The hysteresis is already on-die; no external resistor network needed. ## Output drives CMOS, push-pull, or TTL loads The output stage is configurable for CMOS, push-pull, or TTL logic levels, so it interfaces directly with most digital inputs — no level shifter or pull-up resistor required. That saves board space and keeps the signal path short, which matters when the 40 ns propagation delay is part of a timing budget. ## Active lifecycle — no obsolescence watch needed The MAX9140AAUK+T carries an Active lifecycle status and is ROHS3 compliant. No last-time-buy or end-of-life notice exists.","metaTitle":"MAX9140AAUK+T General Purpose Comparator, 40ns, SOT-23-5","metaDescription":"Analog Devices MAX9140AAUK+T single general-purpose comparator, 40ns propagation delay, 1.5mV hysteresis, 2.7V-5.5V supply, -40°C to 125°C, SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"General Purpose","Package":"Tape & Reel (TR); Cut Tape (CT)","Hysteresis":"1.5mV","Output Type":"CMOS, Push-Pull, TTL","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"61.41dB CMRR, 61.94dB PSRR","Number of Elements":"1","Operating Temperature":"-40°C ~ 125°C","Propagation Delay (Max)":"40ns","Supplier Device Package":"SOT-23-5","Current - Quiescent (Max)":"400µA","Current - Input Bias (Max)":"0.35µA @ 5V","Voltage - Input Offset (Max)":"6mV @ 5V","Voltage - Supply, Single/Dual (±)":"2.7V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.76","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.76000","currency":"USD"},{"qty":10,"price":"$2.47600","currency":"USD"},{"qty":25,"price":"$2.34040","currency":"USD"},{"qty":100,"price":"$2.02850","currency":"USD"},{"qty":250,"price":"$1.92448","currency":"USD"},{"qty":500,"price":"$1.72684","currency":"USD"},{"qty":1000,"price":"$1.45636","currency":"USD"},{"qty":2500,"price":"$1.38354","currency":"USD"},{"qty":5000,"price":"$1.33153","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX9140-MAX9144.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the MAX9140AAUK+T suitable for 5V single supply operation?","answer":"Yes, the part is rated for single-supply operation from 2.7 V to 5.5 V, so 5 V is within the specified range."},{"question":"What is the propagation delay of the MAX9140AAUK+T?","answer":"The maximum propagation delay is 40 ns.
