Pinout:LM393N Datasheet Philips


The LM393N series consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0mV max. for two comparators 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 operated from a single power supply voltage. The Device series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the Device series will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.
