description
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 a high-impedance state
exists between the two ports.
The SN74CBT3384A is characterized for operation from –40°C to 85°C.
