MM54C914 MM74C914 Hex Schmitt Trigger with Extended Input Voltage
February 1988
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 V
CC
or
ground by at least 10V (V
CC

25V) and is
valuable for applications involving voltage level shifting or
mismatched power supplies
The positive and negative-going threshold voltages V
