Functional Description

The 74VCX162827 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 20-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 imped-

ance mode but this does not interfere with entering new

data into the inputs. The same applies for byte two with

OE3 and OE4.
