The FST16233 is a 16-bit to 32-bit high-speed CMOS TTL-compatible multiplexer/demultiplexer bus switch. It features low on resistance, allowing inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. It can be used in applications where two buses need to be addressed simultaneously. The FST16233 can be used as two 8-bit to 16-bit multiplexers or as one 16-bit to 32-bit multiplexer.
