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.
