Electrical Characteristics
Note 9: Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the compara-
tor will provide a proper output state. The low input voltage state must not be less than −0.3 V
used) at T
Note 10: At output switch point, V
Note 11: For input signals that exceed V
should be used on all inputs that might exceed the positive supply.
Note 12: The output sink current is a function of the output voltage. The LP339 has a bi-modal output section which allows it to sink large currents via a Darlington
connection at output voltages greater than approximately 1.5 V
tion).
