description

The ′BCT623 bus transceiver is designed for

asynchronous communication between data

buses. The control function implementation allows

for maximum flexibility in timing. The ′BCT623

provides true data at its outputs.

This device allows 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. Each

output reinforces its input in this configuration.

When both OEAB and OEBA are enabled and all

other data sources to the two sets of bus lines are

at high impedance, both sets of bus lines (16 in all)

will remain at their last states.

The SN54BCT623 is characterized for operation

over the full military temperature range of ?55°C

to 125°C. The SN74BCT623 is characterized for

operation from 0°C to 70°C.
