This includes, but is not limited to, HighlyAccelerated Stress Test (HAST) or biased 85/85, temperaturecycle, autoclave or unbiased HAST, electromigration, bondintermetallic life, and mold-compound life. Such qualificationtesting should not be viewed as justifying use of this componentbeyond specified performance and environmental limits.EMIT OUTIN+IN–VCC–12348765VCC+COL OUTBAL/STRBBALANCEdescription/ordering informationThe LM211 is a single high-speed voltage comparator. This device is designed to operate from a wide range ofpower-supply voltages, including ±15-V supplies for operational amplifiers and 5-V supplies for logic systems. Theoutput levels are compatible with most TTL and MOS circuits. This comparator is capable of driving lamps or relaysand switching voltages up to 50 V at 50 mA. All inputs and outputs can be isolated from system ground. The outputscan drive loads referenced to ground, VCC+ or VCC–. Offset balancing and strobe capabilities are available, and theoutputs can be wired-OR connected. If the strobe is low, the output is in the off state, regardless of the differentialinput.ORDERING INFORMATIONTA–40°C to 125°CVIO maxAT 25°C3 mVSOIC – DPACKAGE†Tape and reelORDERABLEPART NUMBERLM211QDREPTOP-SIDEMARKINGLM211E†Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available atwww.ti.com/sc/package.Please be aware that an important notice concerning availability, standard warranty, and use in critical applications ofTexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.PRODUCTION DATA information is current as of publication date.Products conform to specifications per the terms of Texas Instrumentsstandard warranty.
