LMV331, LMV393, and LMV339 will typically be used to compare a single signal to a reference or two signals against each other. Many users take advantage of the open drain output to drive the comparison logic output to a logic voltage level to an MCU or logic device. The wide supply range and high voltage capability makes LMV331, LMV393, and LMV33 optimal for level shifting to a higher or lower voltage.
