2003/07/16 ( 1 / 3 ) NJU7108 low power and low offset voltage super small-sized single c-mos comparator general description package information the NJU7108 is a super small-sized package single c-mos comparator with push pull output. the operating voltage is from 1v to 5.5v, and the interface can be connected with most of ttl and c-mos type standard logic ics. furthermore, the input offset voltage is lower than 4mv and the package is super small-sized sc88a, therefore they can be suitable for battery use items and other portable items. features pin configuration single low power supply v dd =1.0~5.5v low offset voltage v io =4mv max low operating current i dd =10ua typ push pull output package outline sc88a c-mos technology equivalent circuit NJU7108f3 (top view) in+ v ss in- v dd out 1 2 34 5 v dd in- out in+ v ss
