The hysteresis band (Figure 25) of the noninverting
configuration is defined as follows:

Figure 25.
When VIN is much less than the voltage at the inverting
input (VREF), then the output is low. R2 can then be viewed
as being connected to ground (Figure 26). To calculate the
voltage required at VIN to trip the comparator high, the
following equation is used:
Vin1 +
Vref (R1 ) R2)
R2
When the output is high, VIN must less than or equal to
VREF (VIN ≤ VREF) before the output will be low again
(Figure 27). The following equation is used to calculate the
voltage at VIN to switch the output back to the low state:
Vin2 +
Vref (R1 ) R2) * VCCR1

Termination of Unused Inputs
Proper termination of unused inputs is a good practice to
keep the output from ‘chattering.’ For example, if one
channel of a dual or quad package is not being used, then the
inputs must be connected to a defined state. The
recommended connections would be to tie one input to VCC
and the other input to ground.
