MM74C914

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 (V CC 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, V Ta and VTb, show low variation with respect to temperature (typ 0.0005V/ßC at VCC e 10V). And the hysteresis, V Ta b VTb t 0.2 V CC is guaranteed.
