General Description
The LCX14 contains six inverter gates each with a
Schmitt trigger input. They are capable of transforming
slowly changing input signals into sharply defined, jitter-
free output signals. In addition, they have a greater noise
margin than conventional inverters.
The LCX14 has hysteresis between the positive-going
and negative-going input thresholds (typically 1.0V)
which is determined internally by transistor ratios and is
essentially insensitive to temperature and supply voltage
variations.
The inputs tolerate voltages up to 7V allowing the inter-
face of 5V, 3V and 2.5V systems.
The 74LCX14 is fabricated with advanced CMOS tech-
nology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
