description

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.

The SN54CBT3383 is characterized for operation over the full military temperature range of –55

°C to 125°C.

The SN74CBT3383 is characterized for operation from 0

°C to 70°C.
