INTEGRATED CIRCUITS LM139/239/239A/339/339A/LM2901/MC 3302 Quad voltage comparator Product specification IC11 Data Handbook 1995 Nov 27 Philips Semiconductors Philips Semiconductors Product specification Quad voltage comparator LM139/239/239A/339/339A /LM2901/MC3302 DESCRIPTION The LM139 series consists of four independent precision voltage comparators, with an offset voltage specification as low as 2.0mV max for each comparator, which 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 they are operated from a single power supply voltage. The LM139 series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the LM139 series will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.
