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

power-Schottky versions of the very popular DM54/74365,

366, 367, and 368 (DM8095, 96, 97, and 98) TRI-STATE

hex buffers.
