Description

These DM74LS645 octal bus transceivers are designed for asynchro-nous two-way communication between data buses. The DM74LS645 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 DM74LS645 so that the buses are effectively isolated.
