Excellent EMI Immunity Rail-to-Rail Input, Open-Drain Output Low power CMOS Comparators

  • Consumer
  • PLP
  • RoHS

The NJU77240/NJU77241 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 typ. This feature is suitable for battery powered application.

The NJU77241 are available in small size package, DFN6-G1 (1616), significantly reducing the required portable application's board area.
