3 Description

The SN74CBTLV3383 provides ten bits of high-speed

bus switching or exchanging. The low on-state

resistance of the switch allows connections to be

made with minimal propagation delay.

The device operates as a 10-bit bus switch or as a 5-

bit bus exchanger, which provides swapping of the A

and B pairs of signals. The bus-exchange function is

selected when BX is high, and BE is low.

This device is fully specified for partial-power-down

applications using Ioff. The Ioff feature ensures that

damaging current will not backflow through the device

when it is powered down. The device has isolation

during power off.
