Working Principles

The SN74CBT6845CDWRE4 is a digital multiplexer/demultiplexer IC that operates by selectively connecting one of the eight input/output channels to the common I/O pin based on the channel select inputs (A0-A2 or B0-B2). The output enable (OE) input controls the state of the I/O pin, enabling or disabling the data transfer. When the OE input is high, the outputs are in a high-impedance state.

Detailed Application Field Plans

The SN74CBT6845CDWRE4 can be used in various applications, including:

1. Data communication systems
2. Digital audio/video equipment
3. Computer peripherals
4. Industrial control systems
5. Test and measurement instruments
