DESCRIPTION  
The 74ALVCH16244 is a low voltage CMOS 16  
BIT BUS BUFFER (NON INVERTED) fabricated  
with sub-micron silicon gate and five-layer metal  
2
wiring C MOS technology. It is ideal for low power  
and very high speed 1.65 to 3.6V applications; it  
can be interfaced to 3.6V signal environment for  
both inputs and outputs.  
Any nG output control governs four BUS  
BUFFERS. Output Enable input (nG) tied together  
gives full 16-bit operation.  
When nG is LOW, the outputs are enabled. When  
nG is HIGH, the output are in high impedance  
state.  
Active bus-hold circuitry is provided to hold  
unused or floating data inputs at a valid logic level.  
This device is designed to be used with 3 state  
memory address drivers, etc.  
All inputs and outputs are equipped with  
protection circuits against static discharge, giving  
them 2KV ESD immunity and transient excess  
voltage.
