HEX INVERTER SCHMITT TRIGGER
General Description
The F14 contains six logic inverters which accept standard TTL input signals and provide
standard TTL output levels. They are capable of transforming slowly changing input
signals into sharply defined, jitter-free output signals. In addition, they have greater
noise margin than conventional inverters.
Each circuit contains s Schmitt trigger followed by a Darlington level shifter and a phase
splitter driving a TTL totem-pole output. The Schmitt trigger uses positive feedback to
effectively speed-up slow input transistion, and provide different input threshold
voltages for positive and negative-going transitions. This hysteresis between the
positive-going and negative-going input thresholds (typically 800 mV) is determined
internally by resistor ratios and is essentially insensitive to temperature and supply
voltage variations.
