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.
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.
