Functional Description
The 74ALVCH162244 contains sixteen non-inverting buffers with 3-STATE outputs. The device is nibble (4 bits) controlled
with each nibble functioning identically, but independent of each other. The control pins may be shorted together to obtain
full 16-bit operation.The 3-STATE outputs are controlled by an Output Enable (OE
are in the 2-state mode. When OE
