DescriptionThese octal bus transceivers are designed for
asynchronous two-way communication between data
buses. The control-function implementation minimizes
external timing requirements.
The SNx4LS245 devices allow data transmission
from theA busto theB busor from theB busto the bus, depending on the logic levelat the direction-
control (DIR) input. The output-enable (OE) input can
disable the device so that the buses are effectively
isolated.
Device Information(1)(1) Forall available packages, see the orderable addendumat
the endofthe data sheet.
