Working Principles

The SN74CBTD3861DBRG4 is a digital multiplexer/demultiplexer IC that operates by selectively routing digital signals between multiple input/output channels. It utilizes CMOS technology to achieve high-speed switching while consuming minimal power.

The device features bidirectional data transmission, allowing it to function as both a multiplexer and a demultiplexer. The select inputs (S0-S3) determine the channel to be connected, while the output enable (OE) pin controls the direction of data flow.

When the OE pin is low, the selected input channel is connected to the corresponding bidirectional I/O pin. Conversely, when the OE pin is high, the I/O pins are in a high-impedance state, effectively isolating them from the selected channel.
