Working Principles

The PI5C3244SE is designed using CMOS technology, allowing bidirectional signal switching between two voltage domains. It features a set of four independent switch channels, each capable of connecting an input pin to an output pin or isolating them. The device also incorporates level shifting circuitry, enabling seamless interfacing between logic families operating at different voltage levels.

When the Output Enable (OE#) pin is low, the switches are enabled, and the inputs (A1-A4) are connected to the corresponding outputs (B1-B4). Conversely, when OE# is high, the switches are disabled, and the inputs are isolated from the outputs.
