Working Principles

The 74CB3T3383DBQRG4 is a digital multiplexer/demultiplexer IC that performs logic level translation between two voltage domains. It features eight bidirectional channels, allowing data to be transmitted in both directions. The channel selection inputs (A0-A2 and B0-B2) determine the active channel, while the OE (Output Enable) input controls the output state.

When the OE input is low, the selected channel's input is connected to the corresponding output. Conversely, when the OE input is high, all outputs are in a high-impedance state. This enables multiple devices to share a common bus without interfering with each other.
