description/ordering information
The SN74CBT3384A provides ten bits of
high-speed TTL-compatible bus switching. The
low on-state resistance of the switch allows
connections to be made with minimal propagation
delay.
The device is organized as two 5-bit switches with
separate output-enable (OE) inputs. When OE is
low, the switch is on, and port A is connected to
port B. When OE is high, the switch is open, and
the high-impedance state exists between the two
ports.
