Product Summary
These octal bus transceivers are designed for asynchronous two-way communication between data buses. Thecontrol-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 uponthe logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable thedevice so that the buses are effectively isolated.
Parametrics
