february 2006 rev. 6 1/15 15 lm193, lm193a, lm293, lm293a, lm393, lm393a low power dual voltage comparators 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. n dip8 (plastic package) d so-8 (plastic micropackage) pin connections (top view) p tssop8 (thin shrink small outline package) s mini so-8 (plastic micropackage) 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 + www.st.com
