Functional Description
The 74VCXH16240 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 con-

LOW, the outputs are in the 2-state mode. When OE
HIGH, the standard outputs are in the high impedance
mode but this does not interfere with entering new data into
the inputs.
