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