Octal Bus Switch
TTL-compatible bus switching in a standard ’245 device pinout.
The low on-state resistance of the switch allows connections to be
made with minimal propagation delay.
enable ( OE ) is low, the switch is on and port A is connected to
port B. When OE is high, the switch is open and a
high-impedance state exists between the two ports.
