Octal Bus Transceivers With 3-state Outputs

  These octal bus Transceivers are designed for asynchronous 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 (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 SN54F623 is characterized for operation over the full military temperature range of ? 55?C to 125?C. The SN74F623 is characterized for operation from 0?C to 70?C.
