Working Principles

The SN74CBTLV3251DBQR operates as a multiplexer/demultiplexer by selectively routing digital signals between multiple input/output channels. The channel selection pins (S0-S7) determine the active channel, while the enable pins (EN and OE) control the overall operation.

When a specific channel is selected, the corresponding input/output pin (I/O0-I/O3) is connected to the common output pin (COM). This allows the transmission of digital signals from the selected channel to the output or vice versa.
