These quadruple 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  
output-enable (OEBA and OEAB) inputs. The  
output-enable inputs can be used to disable the  
device so that the buses are effectively isolated.

The dual-enable configuration gives the  
quadruple bus transceivers the capability to store  
data by simultaneously enabling OEBA and  
OEAB. Each output reinforces its input in this  
transceiver configuration. When both control  
inputs are enabled and all other data sources to  
the two sets of bus lines are at high impedance,  
both sets of bus lines (eight in all) retain their  
states. The 4-bit codes appearing on the two sets  
of buses are identical.
