january 2005 revision 2 1/13 wide single supply voltage range or dual supplies : +2v to +36v or 1v to 18v very low supply current (0.4ma) independent of supply voltage (1mw/ comparator at +5v) low input bias current: 25na typ. low input offset current: 5na typ. low input offset voltage: 1mv typ. input common-mode voltage range includes ground low output saturation voltage: 250mv typ. (io = 4ma) differential input voltage range equal to the supply voltage ttl, dtl, ecl, mos, cmos compatible outputs description these devices consist of two independent low voltage comparators designed specifically to operate from a single supply over a wide range of voltages. operation from split power supplies is also possible. 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. pin connections (top view) order code d so-8 (plastic micropackage) n dip-8 (plastic package) s mini so-8 (plastic micropackage) p tssop8 (thin shrink small outline package) 1 2 3 45 6 7 8 - + - + 1 - output 1 2 - inverting input 1 3 - non-inverting input 1 4 - v cc - 5 - non-inverting input 2 6 - inverting input 2 7 - output 2 8 - v cc + part number temperature range package packaging lm193ad/lm193adt -55c, +125c so tube or tape & reel lm193an dip tube lm193d/lm193dt so tube or tape & reel lm193n dip tube lm293ad/lm293adt -40c, +105c so tube or tape & reel lm293an dip tube lm293d/lm293dt so tube or tape & reel lm293n dip tube lm293pt tssop (thin shrink outline package) tape & reel lm293st mini so tape & reel LM393AD/LM393ADt 0c, +70c so tube or tape & reel lm393d/lm393dt so tube or tape & reel lm393n dip tube lm393pt tssop (thin shrink outline package) tape & reel lm393st mini so tape & reel lm193, a lm293, a - lm393, a low power dual voltage comparators
