Three-state Logic - Alternatives To Three-state Bus

Alternatives To Three-state Bus

A three-state bus is typically used between chips on a single printed circuit board (PCB), or sometimes between PCBs plugged into a common backplane.


Usage of three-state logic is not recommended for on-chip connections but rather for inter-chip connections.

Three-state buffers used to enable multiple devices to communicate on a data bus can be functionally replaced by a multiplexer. That will help select output from a range of devices and write one to the bus.

Famous quotes containing the words alternatives to, alternatives and/or bus:

    The literal alternatives to [abortion] are suicide, motherhood, and, some would add, madness. Consequently, there is some confusion, discomfort, and cynicism greeting efforts to “find” or “emphasize” or “identify” alternatives to abortion.
    Connie J. Downey (b. 1934)

    Clearly, society has a tremendous stake in insisting on a woman’s natural fitness for the career of mother: the alternatives are all too expensive.
    Ann Oakley (b. 1944)

    Literature transforms and intensifies ordinary language, deviates systematically from everyday speech. If you approach me at a bus stop and murmur “Thou still unravished bride of quietness,” then I am instantly aware that I am in the presence of the literary.
    Terry Eagleton (b. 1943)
