Each multiplexer has four multiplexer inputs (I0 and I3), an active LOW enable input (E) and a multiplexer output (O). When HIGH, E forces O of the respective multiplexer LOW, independent of the select inputs (S0 to S1) and I0 to I3. When E is LOW, S0 and S1 determine which multiplexer input (I0 to I3) on each of the multiplexers is routed to the respective multiplexer output (O). HEF4539B MSI Fig.1 Functional diagram.
