The PI5C16292 and PI5C162292 are 12-bit to 24-bit Mux/Demux Bus switches designed with a low ON resistance allowing inputs to be connected directly to outputs. The PI5C162292 device has a built-in 25-ohm series resistor to reduce noise resulting from reflections, thus eliminating the need for an external terminating resistor. A2 port is not externally connected and, as a result, has an internal 500-ohm pulldown resistor to ground.
