Functional Description
The 74VCX16240 contains sixteen 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
