Abstract
Programmable logic arrays can be formed utilizing emitter coupled logic. Input terminals and control terminals associated with a programmable logic array module are coupled to the input terminals of a predetermined set of OR circuit means within the module. The outputs of the OR circuit means are coupled to various input terminals of a number of AND gates within the module. The outputs of the AND gates are coupled respectively to output terminals associated with the programmable logic array. The OR circuit means and the AND gates are coupled together in an emitter coupled logic format.
