The open-drain lets you wire-OR multiple outputs or pull to a different rail than the supply — useful for level-shifting or driving a logic input at 3.3 V while the comparator runs from 5 V or 12 V. ## 84 dB CMRR and 5 pA input bias — signal-chain fit Typical CMRR of 84 dB keeps the threshold accurate when the common-mode voltage shifts — relevant for sensor thresholding or zero-crossing detection in noisy environments. Maximum input bias current of 5 pA at 5 V means the comparator does not load high-impedance sources like pH probes or photodiode amplifiers. ## 4.5 µs propagation delay — speed ceiling for switching Maximum propagation delay of 4.5 µs sets the upper frequency for clean output transitions. Below roughly 110 kHz you get full-swing edges; above that the output may not reach the rail before the next transition. For faster loops, consider the TLC372MDR differential comparator. ## 100 µA quiescent current — low-power bias Maximum quiescent current of 100 µA across all four comparators — about 25 µA per channel. That keeps the thermal budget low in a 14-SOIC and makes the part viable for battery-powered threshold monitors or always-on window detectors. ## 3 V to 16 V supply — single or dual rails Supply range from 3 V to 16 V covers single-supply designs (3.3 V, 5 V, 12 V) and dual-supply configurations (±1.5 V to ±8 V). The 20 mA typical output current is enough to drive a logic gate input or a small LED indicator directly. This is a commercial-grade part — fine for office equipment, appliances, and indoor industrial control panels. Not rated for automotive or extended industrial environments; for those, look at the TLC372MDR which covers -55°C to 125°C.","metaTitle":"TLC339CNSR Quad Comparator – TI LinCMOS, 14-SOIC, Active","metaDescription":"Texas Instruments TLC339CNSR quad general-purpose comparator, LinCMOS series, 84 dB CMRR, 4.5 µs propagation delay, 100 µA quiescent current.","metaKeywords":null},"attributes":{"series":"LinCMOS™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Type":"General Purpose","Series":"LinCMOS™","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"CMOS, Open-Drain","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"84dB CMRR","Number of Elements":"4","Operating Temperature":"0°C ~ 70°C","Current - Output (Typ)":"20mA","Propagation Delay (Max)":"4.5µs","Supplier Device Package":"14-SO","Current - Quiescent (Max)":"100µA","Current - Input Bias (Max)":"5pA @ 5V","Voltage - Input Offset (Max)":"5mV @ 10V","Voltage - Supply, Single/Dual (±)":"3V ~ 16V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.57","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.57000","currency":"USD"},{"qty":10,"price":"$1.40700","currency":"USD"},{"qty":25,"price":"$1.32760","currency":"USD"},{"qty":100,"price":"$1.13120","currency":"USD"},{"qty":250,"price":"$1.06212","currency":"USD"},{"qty":500,"price":"$0.92936","currency":"USD"},{"qty":1000,"price":"$0.77004","currency":"USD"},{"qty":2000,"price":"$0.75150","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/074b4c0a8373bf7940c6d36efc02be2d.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLC339CNSR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLC339CNSR when reusing this data.
