74ALVCH16240  
Low-Voltage 16-Bit Buffer  
with Bus Hold 1.8/2.5/3.3 V  
(3–State, Inverting)  
The 74ALVCH16240 is an advanced performance, inverting 16–bit  
buffer. It is designed for very high–speed, very low–power operation  
in 1.8 V, 2.5 V or 3.3 V systems.

MARKING DIAGRAM  
The 74ALVCH16240 is nibble controlled with each nibble  
functioning identically, but independently. The control pins may be  
tied together to obtain full 16–bit operation. The 3–state outputs are  
controlled by an Output Enable (OEn) input for each nibble. When  
OEn is LOW, the outputs are on. When OEn is HIGH, the outputs are  
in the high impedance state. The data inputs include active bus–hold  
circuitry, eliminating the need for external pull–up resistors to hold  
unused or floating inputs at a valid logic state.
