description  
The ′BCT620A bus transceiver is designed for  
asynchronous communication between data  
buses. Thecontrolfunctionimplementationallows  
for maximum flexibility in timing. The ′BCT620A  
provides inverted data at its outputs.

(TOP VIEW)  
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 (OEAB and OEBA) 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  
transceivers the capability of storing data by  
simultaneously enabling OEAB and OEBA. When  
both OEAB and OEBA are enabled and all other  
datasourcestothetwosetsofbuslinesareathigh  
impedance, both sets of bus lines (16 in all) will  
remain at their last states. In this way, each output  
reinforces its input in this configuration.

The SN54BCT620A is characterized for operation  
over the full military temperature range of –55°C  
to 125°C. The SN74BCT620A is characterized for  
operation from 0°C to 70°C.
