Working Principles

The SN74ALVTH162245VR is designed to facilitate the transfer of data between two independent buses operating at different voltage levels. It utilizes a bidirectional transceiver architecture that allows data to flow in both directions simultaneously.

The device incorporates non-inverting level shifting, ensuring that the logic high and low levels are maintained during the translation process. This enables seamless communication between systems operating at different voltage domains.

To prevent bus contention and data corruption, the SN74ALVTH162245VR features a tri-state output control. This allows the device to be effectively disconnected from the bus when not actively transmitting or receiving data.
