Working Principles

The PI3B3245QE is a CMOS-based signal switch that operates by controlling the flow of signals between two ports. When the Output Enable (OE) pin is set to logic high, the switch is enabled, allowing bidirectional signal transmission. Conversely, setting OE to logic low disables the switch, isolating the two ports.
