Operation from dual supplies also is possible if the difference between the two supplies is 2 V to 36 V and VCC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The output can be connected to other open-collector outputs to achieve wired-AND relationships. The TL331I is characterized for operation from –40°C to 85°C. logic diagram IN+ OUT IN– AVAILABLE OPTIONS PACKAGED DEVICE TA VIO(max) AT 25°C SMALL-OUTLINE TRANSISTOR (DBV) –40°C to 85°C 5 mV TL331IDBV The DBV package is only available left-end taped and reeled.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values, except differential voltages, are with respect to the network ground. 2. Differential voltages are at IN+ with respect to IN–. 3. Short circuits from outputs to VCC can cause excessive heating and eventual destruction. 4. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can impact reliability. 5. The package thermal impedance is calculated in accordance with JESD 51. 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 TL331 SINGLE DIFFERENTIAL COMPARATOR SLVS238A – AUGUST 1999 – REVISED NOVEMBER 1999 electrical characteristics at specified free-air temperature, VCC = 5 V (unless otherwise noted) PARAMETER TA† 25°C TEST CONDITIONS VIO Input offset voltage VCC = 5 V to 30 V,, VO = 1.4 V,, VIC = VIC(min) IIO Input offset current VO = 1.4 14V IIB Input bias current VO = 1.4 14V VICR Common-mode input voltage range‡ MIN TYP MAX 2 5 –40°C to 85°C 9 25°C 5 –40°C to 85°C 250 25°C –25 –40°C to 85°C 25°C –40°C to 85°C AVD Large-signal differential voltage amplification VCC = 15 V, VO = 1.4 V to 11.4 V, RL ≥ 15 kΩ to VCC IOH High level output current High-level VOH = 5 V, VOH = 30 V, VID = 1 V VID = 1 V VOL Low level output voltage Low-level IOL = 4 mA, mA VID = –1 1V IOL ICC Low-level output current VOL = 1.5 V, RL = ∞, VID = 1 V VCC = 5 V 25°C –250 –400 0 to VCC–1.5 50 25°C 200 0.1 25°C mV nA nA V 0 to VCC–2 –40°C to 85°C 150 –40°C to 85°C 25°C 50 UNIT V/mV 50 nA 1 µA 400 700 6 mV mA Supply current 25°C 0.4 0.7 mA † All characteristics are measured with zero common-mode input voltage, unless otherwise specified. ‡ The voltage at either input or common-mode should not be allowed to go negative by more than 0.3 V.
