3.0
Descriptions of the pins are listed in
TABLE 3-1:
3.1
The comparator non-inverting and inverting inputs are
high-impedance CMOS inputs with low bias currents.
3.2
This is a CMOS, Schmitt-triggered input that places the
part into a low power mode of operation.
3.3
The comparator outputs are CMOS, open-drain digital
outputs. They are designed to make level shifting and
wired-OR easy to implement.

Typically, these parts are used in a single (positive)
supply configuration. In this case, V
ground and V
need a local bypass capacitor (typically 0.01 µF to
0.1 µF) within 2 mm of the V
bulk capacitor with nearby analog parts (within
100 mm), but it is not required.
