MM74C914 Datasheet Hex Schmitt Trigger

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: MM54C914 MM74C914 Hex Schmitt Trigger with Extended Input Voltage February 1988 MM54C914 MM74C914 Hex Schmitt Trigger with Extended Input Voltage.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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 b 25V to GND a 25V) and is valuable for applications involving voltage level shifting or mismatched power supplies The positive and negative-going threshold voltages VTa and VTb show low variation with respect to temperature (typ 0 0005V C at VCC e 10V) And the hysteresis VTa b VTb t 0 2 VCC is guaranteed
