LM615 - LM615 Quad Comparator and Adjustable Reference

The comparators have an input range which extends to the negative supply and have open-collector outputs Improved over the LM139 series the input stages of the comparators have lateral PNP input transistors which enable low input currents for large differential input voltages and swings above V a Th

• operation over a shunt current range of 17 mA to 20 mA low dynamic impedance broad capacitive load range and cathode terminal voltage ranging from a diode-drop below V b to above V a As a member of National’s Super-Block TM family the LM615 is a space-saving monolithic alternative to a multichip solution offering a high level of integration without sacrificing performance Features.
