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.
