Octal Bus Switch
TTL-compatible bus switching in a standard ’244 device pinout.
The low on resistance of the switch allows connections to be made
with minimal propagation delay.
with separate output-enable (OE) inputs. When OE is low, the
switch is on and data can flow from port A to port B, or vice versa.
When OE is high, the switch is open and a high-impedance state
exists between the two ports.
