Schmitt Triggers
Dual Gate/Hex Inverter
The SN74LS14 contains logic gates/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. Additionally, they have
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 transitions, 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.
