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.
Features
■ Hysteresis: 0.45 VCC (typ.) 0.2 VCCguaranteed
■ Special input protection: Extended Input Voltage Range
■ Wide supply voltage range: 3V to 15V
■ High noise immunity: 0.7 VCC (typ.)
■ Low power TTL compatibility: Fan out of 2 driving 74L
