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.
