P TSSOP14 (Thin Shrink Small Outline Package)
This device consists of four independent precision voltage comparators. All these comparators were designedspecifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible. These comparators also have a unique characteris-tic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage. PIN CONNECTIONS (top view)
