HD74LS642 Octal Bus Transceivers (inverted open-collector outputs) REJ03D0490–0200 Rev.2.00 Feb.18.2005 This octal bus transceivers is designed for asynchronous two-way communication between data buses. The devices transmit data from the A bus to the B bus or from the B bus to the A bus depending upon the level at the direction control (DIR) input. The enable input (G) can be used to disable the device so that the buses are effectively isolated.
