national semiconductor MM54C914/MM74C914 Hex Schmitt Trigger with Extended Input Voltage handbook
The MM54C914-MM74C914 is a monolithic CMOS Hex Schmitt trigger with a 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), which is valuable for applications involving voltage level shifting or mismatched power supplies. The positive and negative-going threshold voltages, VTa and VTb, show low variation with respect to temperature (typ 0.0005V/°C at VCC = 10V), and the hysteresis, VTa - VTb ≥ 0.2 VCC, is guaranteed.
