G control output governs four BUS BUFFERs.  
This device is designed to be used with 3 state  
memory address drivers, etc.  
It has more speed performance at 3.3V than 5V  
AC/ACT family, combined with a lower 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 74LVC244A 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 1.65 to 3.6
