DESCRIPTION
The CBT3384 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.
switching. The low on-state resistance of the switch allows
connections to be made with minimal propagation delay.
The CBT3384 device is organized as two 5-bit bus switches with
separate output-enable (OE) inputs. When OE is LOW, the switch is
on and port A is connected to B. When OE is HIGH, the switch is
open and high-impedance state exists between the two ports.

The CBT3384 is characterized for operation from –40 to +85
