IMPROVED LATCH-UP IMMUNITY  
This device can be used to interface 5V to 3V. It  
combines high speed performance with the true  
CMOS low power consumption.  
All inputs and outputs are equipped with  
protection circuits against static discharge, giving  
them 2KV ESD immunity and transient excess  
voltage.  
DESCRIPTION  
The 74LVX244 is a low voltage CMOS OCTAL  
BUS BUFFER (3-STATE) fabricated with  
sub-micron silicon gate and double-layer metal  
2
wiring C MOS technology. It is ideal for low  
power, battery operated and low noise 3.3V  
applications.
