HEX SCHMITT
General DescriptionThe MM54C914 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.
