Working Principles

The SN74ABT823DBRG4 is designed to translate voltage levels between two different logic families. It uses a combination of MOSFETs and CMOS technology to achieve bidirectional voltage translation. The OE pin controls the direction of data flow by enabling or disabling the output buffers.

When the OE pin is low, the device is enabled, and the data can flow bidirectionally between the A and B ports. When the OE pin is high, the device is disabled, and the outputs are in a high-impedance state.
