The PE42540F with Analog Switches / Multiplexers ROHS manufactured by pSemi is an ultra-low power 4:1 single-pole double-throw (SPDT) multiplexer. It has a flexible voltage range between 1.1V and 5.5V and operates from -40°C to +85°C. The device enables four signals from up to four different signal sources to be routed through a single input to a single output while providing isolation and high accuracy signal routing. The PE42540F also offers great flexibility and performance in Static Time-Base circuits, power source switching, band-selecting, clock multiplexing, TV and radio tuning, and signal filtering. The device has a low distortion, low On-resistance, low power consumption, high impedance, and low EMI. It also features high robustness and durability, making it suitable for high-temperature applications.
