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.

SN54BCT620A . . . FK PACKAGE

(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.
