The PI3B4010 is a 3.3V, 10- to 40-bit demultiplexing/multiplexing bus switch. It is intended for multiple data or address muxing. Industry leading advantages include a propagation delay of 300ps, resulting from the 35-ohm channel resistance, and low I/O capacitance. The A-port multiplexes to one of four or all outputs allowing a complete bank of 10 bits to switch. The switch is bidirectional.
