description
These 10-bit bus transceivers are designed for
asynchronous two-way communication between
data buses. The control function implementation
allows for maximum flexibility in timing.
These 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 levels at the enable
inputs (GBA and GAB).
