Diodes' PI5C3390 and PI5C32390 are 16-to-8 multiplexer/demultiplexer bus switches with a low On-Resistance allowing inputs to be connected directly to outputs. The two enable inputs connecteach of eight I/O to the common I/O pin. This multiplexer function can be used to select and route logic signals to form crossbar switches, isolate bus capacitance, or provide a zero delay switchconnection. The bus switch creates no additional ground bounce noise or additional propagation delay. The PI5C32390 is designed with an internal 25-ohm resistor reducing noise reflection in high-speed applications.
