Figure 2 shows the configuration with no hysteresis when the
HYSTP and HYSTN pins are connected together to V
This configuration is not recommended because it has the
highest level of false triggers due to the system noise.

Figure 3 shows the configuration with symmetric hysteresis
when the HYSTP and HYSTN pins are connected to the same
voltage that is less than V
teresis band around the input threshold voltage V
that the positive band is equal to the negative band.
This configuration controls the false triggering mentioned in
Figure 2. Symmetric hysteresis values less than 5mV to 10
mV are recommended for precise level detection applica-
tions.
