Working Principles

The PI7AT04CEX is a signal switch that routes the input signal from either IN1 or IN2 to the output pin. The selection is controlled through the SPI interface, which communicates with an external microcontroller or SPI master. When the enable (EN) pin is set high, the switch operates according to the SPI commands received.

Detailed Application Field Plans

• Audio/Video Switching Systems: Enables seamless switching between multiple audio/video sources.
• Test and Measurement Equipment: Facilitates signal routing in test setups and data acquisition systems.
• Communication Systems: Used for signal switching in wireless base stations and communication infrastructure.
• Industrial Automation: Allows flexible signal routing in control systems and PLCs.
• Medical Devices: Supports signal switching in medical imaging equipment and diagnostic devices.
