3 Description
These octal bus transceivers are designed for asynchronous two-way munication between data buses. The control-function implementation minimizes external timing requirements.
The SNx4LS245 devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the directioncontrol (DIR) input. The output-enable (OE) input can disable the device so that the buses are effectively isolated.
