VOLTAGE COMPARATOR
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJM311 is a voltage comparator that has low input
currents. It is also designed to operate covering a wider range
of supply voltages from Standard ±15V op amp supplies down
to the single 5V supply used for IC logic. Its output is compatible
with RTL,DTL and TTL as well as MOS circuits. Furthermore, it
can drive lamps or relays, switching voltages up to 40V at
currents as high as 50mA. Offset balancing is provided, and the
outputs can be OR wired.
