Working Principles

The PI5A319AW is based on CMOS technology, which allows for low power consumption and high-speed operation. It utilizes MOSFET transistors as the switching elements. When a control voltage is applied to the appropriate pin, the switch closes, allowing the signal to pass through. Conversely, when the control voltage is removed, the switch opens, isolating the signal.
