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.
