LM239A Datasheet | National Semiconductor

description The LM1~9A series consists of four independent precision voltage parators with an offset voltage specification of 2 m V. max. for all four parators 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 drai A is independent of the magnitude of the power supply voltage. These parators also have a unique characteristic in that the input mon- mode voltage range includes ground, even though operated from a single power supply voltage. Application areas include limit parators, 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 LM 1~9A series was designed to directly interface with TTL and CMOS. When operated from both plus...
