Working Principles

The SN74CBT3251DR is a digital multiplexer/demultiplexer that allows the selection of one out of eight input channels to be routed to a single output. The channel selection is controlled by the A0, A1, A2, and S0, S1 inputs. The OE input enables or disables the outputs. When the OE input is low, the selected channel's input is connected to the output. When the OE input is high, all outputs are disabled.

Detailed Application Field Plans

The SN74CBT3251DR can be used in various applications, including:

1. Data communication systems
2. Audio/video signal routing
3. Test and measurement equipment
4. Industrial automation
5. Automotive electronics
6. Medical devices
7. Consumer electronics
8. Telecommunications
