LOW POWER AND LOW OFFSET VOLTAGE SUPER SMALL-SIZED SINGLE C-MOS COMPARATOR NJU78 GENERAL DESCRIPTION The NJU78 is a super small-sized package single C-MOS comparator with push pull output. The operating voltage is from V 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 mv and Low operating current µa, therefore they can be suitable for battery use items and other portable items. The available package is not only SC88A, but also ultra small package TSON6.
