MM54C914 MM74C914 Hex Schmitt Trigger with Extended Input Voltage
General Description
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 b 25V to GND a 25V) and is valuable for applications involving voltage level shifting or mismatched power supplies The positive and negative-going threshold voltages VT a and VTb show low variation with respect to temperature (typ 0 0005V C at VCC e 10V) And the hysteresis VT a b VTb t 0 2 VCC is guaranteed
