TRI-STATEÉ Octal Buffer
General Description
Thesedevices provide eight,two-input buffersin each pack-
age.All employthe newest low-power-Schottky TTL tech-
nology. Oneofthetwo inputsto each bufferis usedasa
control lineto gatethe output intothe high-impedance
state, while theotherinput passesthe data through thebuff-
er.The ’LS465and ’LS467 presenttrue dataatthe outputs,
whilethe ’LS466 and ’LS468are inverting.Onthe ’LS465
and ’LS466 versions,all eight TRI-STATE enable linesare
common, with access througha 2-input NOR gate.Onthe
’LS467and ’LS468 versions,four buffersare enabled from
one common line,andthe other four buffersare enabled
from another common line.Inall casesthe outputsare
placedinthe TRI-STATE conditionby applyinga high logic
leveltothe enable pins. These devices represent octal,low
power-Schottky versionsofthe very popular DM54/74365,
366, 367,and 368 (DM8095,96,97, and98) TRI-STATE
hex buffers.
