MM74C914 Hex Schmitt Trigger with Extended Input Voltage October 1987 Revised January 1999 MM74C914 Hex Schmitt Trigger with Extended Input Voltage General Description The 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, VT+ and VT−, show low variation with respect to temperature (typ 0.0005V/°C at VCC = 10V). And the hysteresis, VT+ − VT− ≥ 0.2 VCC is guaranteed.
