Low-ohmic single-pole double-throw analog switch

The XS5A1T4157 is a low-ohmic single-pole double-throw analog switch suitable for use as an analog or digital 2:1 multiplexer/demultiplexer. It has a digital select input (S), two inputs/outputs (Y0 and Y1) and a common input/output (Z).

The XS5A1T4157 passes analog and digital voltages that may vary across the full voltage supply range (GND to VCC).
