... Hysteresis rejects noise and prevents oscillations on low-slew input signals. External resistors control hystere- sis levels. HYS1 controls channel 1 and HYS2 controls channel 2, when the MAX9975 is programmed in single- ended compare mode (CDIFF = 0). HYS1 also controls channel 2’s high-comparator output when the MAX9975 is programmed in differential compare mode (CDIFF = 1) ...

... Leaving THR unconnected results in a nominal threshold of 1.25V from an internal reference, providing compatibility with 2.5V to 3.3V logic. Temperature Monitor The MAX9975 supplies a temperature output signal, TEMP, that asserts a 3.33V nominal output voltage at a +70°C (343K) die temperature. The output voltage changes proportionally with temperature at 10mV/°C. ...
