Functional Description
The 74VCX16827 contains twenty non-inverting buffers
with 3-STATE outputs. The device is byte controlled with
each byte 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
Output Enable (OEn) inputs. When OE1, and OE2 are
LOW, O0—O10 are in the 2-state mode. When either OE1
or OE2 are HIGH, the standard outputs are in the high
impedance mode but this does not interfere with entering
new data into the inputs. The same applies for byte two
with OE3 and OE4.
