Precision Analog Switches Nexperia Precision Analog Switches are suitable for use as analog or digital multiplexers/demultiplexers. These switches have low threshold digital inputs, which allow them to be driven by 1.8V logic levels in 3.3V applications without increasing the current supply. This makes it possible for the device to switch 4.3V signals with a 1.8V digital controller, eliminating the need for logic-level translation. Typical applications include appliances, communication systems, medical equipment, analog sensor monitoring, audio routings/switchings, and test measurements.
