SCHMITT TRIGGERS DUAL 4-INPUT
NAND/HEX INVERTERS
The MC54/74F13 and MC54/74F14 contain 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.
