description
The TLV1391 is a differential comparator built using a Texas Instruments low-voltage, high-speed bipolar
process. These devices have been developed specifically for low-voltage, single-supply applications. Their
enhanced performance makes them excellent replacements for the LM393 in the improved 3-V and 5-V system
designs of today.
The TL V1391, with its typical supply current of only 80 µA, is ideal for low-power systems. Response time also
has been improved to 0.7 µs.
The TL V1391C is characterized for operation from 0°C to 70°C and the TL V1391I 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 GND.
2. Differential voltages are at the noninverting input with respect to the inverting input.
3. Short circuits from the outputs to VCC can cause excessive heating and eventual destruction of the chip.
4. Maximum power dissipation is a function of TJ(max),
ambient temperature is PD = (TJ(max) – TA)/
5. The package thermal impedance is calculated in accordance with JESD 51.
