SN54LV245A, SN74LV245A OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS SCLS382N ï SEPTEMBER 1997 ï REVISED AUGUST 2010 description/ordering information (continued) The ’LV245A devices are designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses are effectively isolated.
