Octal Bus Transceivers , Inc

These octal Bus Transceivers LS640 LS641 LS642 LS645 are designed for asynchronous two-way Communication between data buses. Control function implementation minimizes external Timing requirements. These circuits allow data transmis- sion from the A bus to B or from the B bus to A bus depending upon the Logic level of the direction control (DIR) input. Enable input (G) CAN disable the device so that the buses are effectively isolated. By Freescale Semiconductor, Inc
