... The LMV7251/LMV7255 are available in space saving SC-70 or SOT23-5 packages. These comparators are ideal for low voltage and space critical designs. The LMV7251 features a push-pull output stage. This feature allows operation with minimum power consumption when driving a load. The LMV7255 features an open drain output. This allows the connection of an external resistor at the output ...
