General description

It is capable of transforming slowly changing input signals into sharply defined, jitter free

output signals. In addition, it has a 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-going and negative-going inputs. The threshold differential (typically 600 mV)

is determined internally by resistor ratios and is insensitive to temperature and supply

voltage variations.
