Working Principles

The SN74CBT3253CDBR operates based on digital logic principles. The channel selection pins (S1 and S2) determine which input channel is connected to the output. The enable pin (E) activates the IC, allowing data to flow through the selected channel. The output is controlled by the channel enable pins (OE1 and OE2). When a channel is enabled, the corresponding data input/output pin (I/O1 or I/O2) is connected to the output pin. The IC operates at high speed and consumes low power, making it suitable for various digital multiplexing/demultiplexing applications.
