Texas Instruments 54HC245
The control-function implementation minimizes external timing requirements. The 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 direction-control (DIR) input.FEATURES

DESCRIPTION
These octal bus transceivers are designed for asynchronous two-way communication between data buses. The output-enable ( OE) input can be used to disable the device so that the buses are effectively isolated.
