Functional Description

The 74VCX162244 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 (OEn) input. When OEn is LOW, the outputs

are in the 2-state mode. When OEn is HIGH, the standard outputs are in the high impedance mode but this does not inter-

fere with entering new data into the inputs.
