The SN74CBTLV3384 provides ten bits of high-speed bus switching. The low on-state resistance of the switch allows connections to be made with minimal propagation delay.

The device is organized as dual 5-bit bus switches with separate output-enable (OE\) inputs. It can be used as two 5-bit bus switches or one 10-bit bus switch. When OE\ is low, the associated 5-bit bus switch is on and A port is connected to B port. When OE\ is high, the switch is open, and the high-impedance state exists between the two ports.

This device is fully specified for partial-power-down applications using I_off. The I_off feature ensures that damaging current will not backflow through the device when it is powered down. The device has isolation during power off.
