description
The SN74CBT3384 provides ten bits of
high-speed TTL-compatible bus switching. The
low on resistance of the switch allows connections
to be made without adding 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 a high-impedance state
exists between the two ports.
The SN74CBT3384 is characterized for operation from 0°C to 70°C.
