Vintage AMD LM339AN - Low Power Low Offset Voltage Quad Comparator - RARE
SquareTrade © AP6.0 You are buying a RARE LM339AN made by AMD back in the year of 1984. These are new but old items from a private collection. AMD only made these as a second source of National Semiconductor parts. Quad Voltage Comparators in one package. Normal 0 MicrosoftInternetExplorer4 Normal 0 MicrosoftInternetExplorer4 Normal 0 MicrosoftInternetExplorer4 Normal 0 MicrosoftInternetExplorer4 Normal 0 MicrosoftInternetExplorer4 Normal 0 MicrosoftInternetExplorer4 The LM339 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 ... moremagnitude 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 LM339 series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies. They will directly interface with MOS logic— where the low power drain of the LM339 is a distinct advantage over standard comparators. Plastic 14 pin DIP case with standard leads. These are new.
