NJU7141
LOW-VOLTAGE OPERATION TINY SINGLE CMOS COMPARATOR
■ GENERAL DESCRIPTION
The NJU7141 is a low voltage single-power-supply operation
single CMOS comparator with open drain output.
The NJU7141 operated from 1 to 5.5V supply and interface
with most of TTL and CMOS type standard logic ICs.
The NJU7141 is in SOT−23−5 package, and it is suitable for
battery use items and other portable system.

( note1 ) If the supply voltage ( VDD ) is less than 7V, the input voltage must not over the VDD level though 7V is limit
specified.
( note2 ) Decoupling capacitor should be connected between VDD and VSS due to the stabilized operation for the circuit.
