The Texas Instruments SN74CBT3383CDW is a Bus FET Exchange Switch from the 74CBT logic family. It implements a 5 x 2:2 switching matrix — five independent channels, each routing one of two inputs to the corresponding output, with an exchange function that lets you swap the signal paths. This is not a simple multiplexer; the exchange topology allows bidirectional signal swapping between two buses, which is useful for cross-connecting data lines or reconfiguring a parallel bus without adding external logic. Packaged in a 24-SOIC (0.295", 7.50mm width) surface-mount body, it shares the standard 24-SOIC footprint used across many TI bus-switch and logic devices.
5 x 2:2 — what the circuit count means for your bus
The 5 x 2:2 configuration means five independent switch sections, each with two inputs and two outputs arranged so the bus lines can be exchanged. In a typical application, you route a set of data or address lines through the switch, and the exchange control lets you swap the two sides — useful for correcting a board-level routing error or implementing a dynamic bus reconfiguration. Because the switch is bidirectional, signal flow can go either way, which simplifies the board layout.
It is ROHS3 compliant.
