3 Description

The SN74CBT3383 and SN54CBT3383 devices

provide ten bits of high-speed TTL-compatible

bus switching or exchanging. The low ON-state

resistance of the switch allows connections to be

made with minimal propagation delay.

The devices operate as a 10-bit bus switch or 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. The

switches are connected when BE is low.
