description/ordering information
LP239, LP339, LP2901 low-power quadruple differential comparators. Each device consists four independent voltage comparators designed specifically operate from single power supply typically draw 60-µA drain current over wide range voltages. Operation from split power supplies also possible ultra-low power-supply drain current independent power-supply voltage. Applications include limit comparators, simple analog-to-digital converters, pulse generators, squarewave generators, time-delay generators, voltage-controlled oscillators, multivibrators, high-voltage logic gates. LP239, LP339, LP2901 were designed specifically interface with CMOS logic family. ultra-low power-supply current makes these products desirable battery-powered applications. LP239 characterized operation from -25°C 85°C. LP339 characterized operation from 70°C. LP2901 characterized operation from -40°C 85°C. ORDERING INFORMATION
