Product Summary

The MM74C914N is a monolithic CMOS Hex Schmitt trigger with special input protection scheme. The MM74C914N allows the input voltage levels to exceed VCC or ground by at least 10V (VCC b 25V to GND - 25V), and is valuable for applications involving voltage level shifting or mismatched power supplies. The positive and negative-going threshold voltages, VT+ and VT-, show low variation with respect to temperature (typ 0.0005V/℃ at VCC = 10V). And the hysteresis, VT+ - VT- ≥ 0.2 VCC is guaranteed.
