NTE74LS641 Description
The NTE74LS641 is an octal bus transceiver in a 20−Lead DIP type package designed for asynchronous two−way munication between data buses. This device transmits 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 pin (G) can be used to disable the device so the buses are effectively isolated.
