74LCX14
Low Voltage Hex Inverter
with 5V Tolerant Schmitt Trigger Inputs
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 out-
put 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 interface
of 5V, 3V and 2.5V systems.
The 74LCX14 is fabricated with advanced CMOS technol-
ogy to achieve high speed operation while maintaining
CMOS low power dissipation.
