74LCX14
Low Voltage Hex Inverter
with 5V Tolerant Schmitt Trigger Inputs
General Description
Features
■ 5V tolerant inputs
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.
■ 2.3V–3.6V VCC specifications provided
■ 6.5 ns tPD max (VCC 3.3V), 10 A ICC max
■ Power down high impedance inputs and outputs
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.
■ 24 mA output drive (VCC 3.0V)
■ Implements patented noise/EMI reduction circuitry
■ Latch-up performance exceeds JEDEC 78 conditions
■ ESD performance:
The inputs tolerate voltages up to 7V allowing the interface
of 5V, 3V and 2.5V systems.
Machine model 200V
Human model 2000V
The 74LCX14 is fabricated with advanced CMOS technol-
ogy to achieve high speed operation while maintaining
CMOS low power dissipation.
