february 2010 doc id 2164 rev 11 1/16 16 lm193, lm293, lm393 low power dual voltage comparators features wide single-supply voltage range or dual supplies: +2 v to +36 v or 1 v to 18 v very low supply current (0.4 ma) independent of supply voltage (1 mw/comparator at +5 v) low input bias current: 25 na typ. low input offset current: 5 na typ. low input offset voltage: 1 mv typ. input common-mode voltage range includes ground low output saturation voltage: 250 mv typ. (i sink =4ma) differential input voltag e 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. dip8 (plastic package) so-8 (plastic micropackage) pin connections (top view) tssop8 (thin shrink small outline package) miniso-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
