■GENERAL DESCRIPTION
The NJU77240/NJU77241/NJU77242 are Rail-to-Rail
Input CMOS comparators featuring Low-power and Open-
Drain output.
These comparators operate from 1.8V to 5.5V and low
supply current of 6µA/ch.typ. This feature is suitable for
battery powered application.
The NJU77241/NJU77242 are available in small size
Package, DFN6-G1(1616), DFN8-U1(2020), significantly
reducing the required portable application's board area.

(1) The absolute maximum input voltage is limited at 7V.
(2) Input voltages outside the supply voltage will be clamped by ESD protection diodes. If the input voltage exceeds the supply voltage,
the input current must be limited 10 mA or less by using a restriction resistance.
(3) Differential voltage is the voltage difference between +INPUT and - INPUT.
For supply voltage less than +7V, the absolute maximum rating is equal to the supply voltage.
(4) The absolute maximum of Output Terminal Input Voltage is limited at 7V.
