Hex TRI-STATE Buffers
General Description
This device contains six independent gates each of which
performs a non-inverting buffer function The outputs have
the TRI-STATE feature When enabled the outputs exhibit
the low impedance characteristics of a standard LS output
with additional drive capability to permit the driving of bus
lines without external resistors When disabled both the
output transistors are turned off presenting a high-imped-
ance state to the bus line Thus the output will act neither as
a significant load nor as a driver To minimize the possibility
that two outputs will attempt to take a common bus to oppo-
site logic levels the disable time is shorter than the enable
time of the outputs
Features
Y Alternate military aerospace device (54LS367A) is
available Contact a National Semiconductor sales of-
fice distributor for specifications

parametric values defined in the ‘‘Electrical Characteristics’’
table are not guaranteed at the absolute maximum ratings
