Hex TRI-STATEÉ Inverting Buffers
General Description
This device containssix independent gates eachof which
performsan inverting buffer function.The outputs havethe
TRI-STATE feature. When enabled,the outputs exhibitthe
low impedance characteristicsofa standardLS outputwith
additional drive capabilityto permitthe drivingofbus lines
without external resistors. When disabled, boththe output
transistorsareturnedoff presentinga high-impedance statethebus line. Thusthe outputwillact neitherasa signifi-
cantloadnorasa driver.To minimizethe possibility thattwo
outputswill attemptto takea commonbusto opposite logic
levels,the disabletimeis shorter thanthe enable timeofthe
outputs.
Features Alternate Military/Aerospace device (54LS368)is avail-
able. Contacta National Semiconductor Sales Office/
Distributorfor specifications.
