General Description
This device containssix independent gates eachof which
performsa non-inverting buffer function. The outputs have
the TRI-STATE feature. When enabled,the outputs exhibit
thelow impedance characteristicsofa standardLS output
with additional drive capabilityto permitthe drivingofbus
lines without external resistors. When disabled, boththe
output transistorsare turnedoff presentinga high-imped-
ance statetothebus line. Thus theoutput willact neitheras significant loadnorasa driver.To minimizethe possibility
thattwo outputswill attemptto takea commonbusto oppo-
site logic levels,the disable timeis shorter thanthe enable
timeofthe outputs.
Features Alternate Military/Aerospace device (54LS365A)is
available. Contacta National Semiconductor SalesOf-
fice/Distributorfor specifications.
