Working Principles

The SN74AVCBH164245KR is a bidirectional voltage-level translator that allows seamless communication between devices operating at different voltage levels. It utilizes a combination of level-shifting circuits and automatic direction control to ensure proper signal translation.

When the DIR pin is set to a specific logic level, the device automatically determines the direction of data flow. The OEAB and OEBA pins are used to enable or disable the output drivers, controlling the bidirectional data transmission.

The internal level-shifting circuitry ensures that the input signals from one voltage domain are translated to the appropriate voltage levels of the other domain. This enables reliable and accurate data transfer between devices with different voltage requirements.
