description/ordering information
The LP239, LP339, LP2901 are low-power quadruple dierential comparators. Each device consists of four
independent voltage comparators designed specifically to operate from a single power supply and typically to
draw 60-µA drain current over a wide range of voltages. Operation from split power supplies also is possible
and the ultra-low power-supply drain current is independent of the power-supply voltage.
Applications include limit comparators, simple analog-to-digital converters, pulse generators, squarewave
generators, time-delay generators, voltage-controlled oscillators, multivibrators, and high-voltage logic gates.
The LP239, LP339, LP2901 were designed specifically to interface with the CMOS logic family. The ultra-low
power-supply current makes these products desirable in battery-powered applications.
The LP239 is characterized for operation from −25° °C to 85 C. The LP339 is characterized for operation from
0 C.°C to 70°C. The LP2901 is characterized for operation from −40°C to 85°

†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 in the 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. This input current only exists when the voltage at any of the inputs is driven negative. The current flows through the collector-base
junction of the input clamping device. In addition to the clamping device action, there is lateral n-p-n parasitic transistor action. This
action is not destructive, and normal output states are reestablished when the input voltage returns to a value more positive than
− 0.3 V at T
A = 25°C.
4. Short circuits between outputs to V
CC can cause excessive heating and eventual destruction.
5. If the output transistors are allowed to saturate, the low-bias dissipation and the on-o characteristics of the outputs keep the
dissipation very small (usually less than 100 mW).
6. Maximum power dissipation is a function of T
J(max), θJA, and TA. The maximum allowable power dissipation at any allowable
ambient temperature is P
D = (TJ(max) − T
A)/θ
JA . Operating at the absolute maximum T
J of 150°C can impact reliability.
7. The package thermal impedance is calculated in accordance with JESD 51-7.

NOTES: 8. VIO is measured over the full common-mode input voltage range.
9. Because of the p-n-p input stage, the direction of the current is out of the device. This current essentially is constant (i.e., independent
of the output state). No loading change exists on the reference or input lines as long as the common-mode input voltage range is
not exceeded.
10. The output sink current is a function of the output voltage. These devices have a bimodal output section that allows them to sink
(via a Darlington connection) large currents at output voltages greater than 1.5 V, and smaller currents at output voltages
less than 1.5 V.
