TRI-STATE Octal Buffer
General Description
These devices provide eight two-input buffers in each pack-
age All employ the newest low-power-Schottky TTL tech-
nology One of the two inputs to each buffer is used as a
control line to gate the output into the high-impedance
state while the other input passes the data through the buff-
er The ’LS465 and ’LS467 present true data at the outputs
while the ’LS466 and ’LS468 are inverting On the ’LS465
and ’LS466 versions all eight TRI-STATE enable lines are
common with access through a 2-input NOR gate On the
’LS467 and ’LS468 versions four buffers are enabled from
one common line and the other four buffers are enabled
from another common line In all cases the outputs are
placed in the TRI-STATE condition by applying a high logic
level to the enable pins These devices represent octal low
