The MM54C914/MM74C914 is a monolithic CMOS Hex Schmitt trigger with special input protection scheme. This scheme allows the input voltage levels to exceed VCC or ground by at least 10V (VCC - 25V to GND + 25V), and is valuable for applications involving voltage level shifting or mismatched power supplies.
The positive and negative-going threshold voltages of MM54C914, VT+ and VT-, show low variation with respect to temperature (typ 0.0005V/ at VCC = 10V). And the hysteresis, VT+ b VT- t 0.2 VCC is guaranteed.
