The ’CBT3383 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.
