Abstract
An improved multiplexer circuit features an addressing arrangement for effecting the selection, first, of the particular multiplexing module, then of an individual input from among the several inputs to the module. To this end, a latch assembly is provided for storing the address of the individual input to the module. Gating structure is provided, responsive to an address code for enabling the latch assembly to store the applied address code. An output switch is connected in the output circuit of the multiplexer module and operatively controlled by the selecting circuit to block any spurious output from the multiplexer module when the particular multiplexer is not selected.
