LM139/LM239/LM339/LM2901/LM3302 Low Power Low Offset Voltage Quad Comparators
General Description
The LM139 series consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV max for all four comparators.

These were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage. Application areas include limit comparators, simple analog to digital converters; pulse, squarewave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. The LM139 ser

LM139/LM239/LM339 A Quad of Independently Functioning Comparators
Introduction
The LM139/LM239/LM339 family of devices is a monolithic quad of independently functioning comparators designed to meet the needs for a medium speed, TTL compatible comparator for industrial applications. Since no antisaturation clamps are used on the output such as a Baker clamp or other active circuitry, the output leakage current in the OFF state is typically 0.5 nA. This makes the device ideal for system applications where it is desired to switch a node to ground while leaving it totally unaffected in the OFF state. Other features include single supply, low voltage operation with an input common mode range from ground up to approximately one volt below VCC. The output is an uncommitted collector so it may be used with a pull-up resistor and a separate output supply to give switching levels from any voltage up to 36V down to a VCE SAT abov
