00/08/29 ( 1 / 5 ) NJU7108/09 low power and low offset voltage super small-sized single c-mos compalator ! general description ! package information the NJU7108/09 are super small-sized package single c-mos comparators 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 (see line-up) " push pull output " package outline sc88a " c-mos technology ! line-up (v dd =3.0v,ta=25 c) parameter NJU7108 nju7109 unit operating current (i dd ) 10 100 ua(typ) propagation delay (t plh /t phl ) 500/190 110/70 ns(typ) output signal rising time falling time (t tlh /t thl ) 10/5 5/4 ns(typ) ! equivalent circuit nju710xf2 preliminar y (top view) in+ v ss in- v dd out 1 2 3 4 5 v dd in- out in+ v ss
