- P/N: 74F14
- Hex Schmitt trigger inverters
The 74F14 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 a greater noise margin than conventional
inverters. Each circuit contains a 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 transition,
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.
