74LCX14  
Low Voltage Hex Inverter with 5V Tolerant  
Schmitt Trigger Inputs  
Features  
General Description  
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 output signals. In addition, they have a greater noise  
margin than conventional inverters.  
2.3V–3.6V V specifications provided  
CC  
6.5ns t max. (V = 3.3V), 10µA I max.

Power down high impedance inputs and outputs  
24mA output drive (V = 3.0V)  
CC  
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.  
Implements patented noise/EMI reduction circuitry  
Latch-up performance exceeds JEDEC 78 conditions  
ESD performance:  
– Human body model > 2000V  
– Machine model > 200V  
The inputs tolerate voltages up to 7V allowing the inter-  
face of 5V, 3V and 2.5V systems.  
Leadless DQFN package  
The 74LCX14 is fabricated with advanced CMOS tech-  
nology to achieve high speed operation while maintain-  
ing CMOS low power dissipation.
