description

The octal bus transceiver is designed for asynchronous two-way communication between data buses. The

control-function implementation minimizes external timing requirements.

The device allows 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. The output-enable (OE) input can be used to disable the

device so that the buses are effectively isolated.

The 74ACT11245 is characterized for operation from –40°C to 85°C.
