DM74ALS645A Octal Bus Transceivers
General Description
These octal bus transceivers are designed for asynchronous two-way communication between data busses.
These 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 the busses are effectively isolated.
Features
