description
This device consists of a single voltage comparator that is designed to operate from a single power supply over
a wide range of voltages. 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.

†
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. 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),
θ
JA
, and TA. The maximum allowable power dissipation at any allowable
ambient temperature is PD = (TJ(max) – TA)/
θ
JA
. Operating at the absolute maximum TJ of 150°C can impact reliability.
5. The package thermal impedance is calculated in accordance with JESD 51.
