Working Principles

The SN74AVC4T245DRG4 is designed to translate signals between two voltage domains, allowing components operating at different voltage levels to communicate with each other. It utilizes a combination of level-shifting circuitry and bi-directional buffers to achieve this functionality. The direction of signal flow is controlled by the OE# pin, which enables or disables the output drivers.
