description/ordering information
These octal bus transceivers are designed for
asynchronous two-way communication between
data buses. The control-function implementation
minimizes external timing requirements.
The 鈥橦CT245 devices allow data transmission
from the A bus to the B bus or from the B bus to the
A bus, depending upon the logic level at the
direction-control (DIR) input. The output-enable
(OE) input can be used to disable the device so
that the buses are effectively isolated.
