MM74C914 Hex Schmitt Trigger with Extended Input
Voltage
General Description
The 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 −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.
