54F 74F14
Hex Inverter Schmitt Trigger
General Description
The ’F14 contains six logic inverters which accept standard
TTL input signals and provide standard TTL output levels
They are capable of transforming slowly changing input sig-
nals into sharply defined jitter-free output signals In addi-
tion they have a greater noise margin than conventional
inverters
Each circuit contains a Schmitt trigger followed by a Darling-
ton level shifter and a phase splitter driving a TTL totem-
pole output The Schmitt trigger uses positive feed back to

effectively speed-up slow input transition and provide differ-
ent input threshold voltages for positive and negative-going
transitions This hysteresis between the positive-going and
negative-going input thresholds (typically 800 mV) is deter-
mined internally by resistor ratios and is essentially insensi-
tive to temperature and supply voltage variations
