DESCRIPTION
This device consists of four independent precision
voltage comparators. All these comparators were
designedspecifically to operate from a single power
supply over a wide range of voltages. Operation
from split power supplies is also possible.
These
characteris-tic in that the input common-mode volt-
age range includes ground even though operated
from a single power supply voltage.
