The APX393/339 are low voltage (2.5V to 5.5V) dual and quad comparators. The APX393 is the dual version available in the 8-pin SOP and MSOP packages. The APX339 is the quad version available in 14-pin TSSOP package. The APX393/339 are designed to efficiently minimize cost, space, and power consumption for portable consumer products. They have open drain output to connect to the logic supply through a pull-up resistor and allow interfacing to a variety of logic families.
