description
These octal bus transceivers are designed for asynchronous communication between data buses. These
devices transmit data from the A bus to the B bus or from the B bus to the A bus depending upon the 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 74AC11640 is characterized for operation from 鈥?40擄C to 85擄C.
