Disadvantages: - Limited number of inputs and outputs - Relatively small package size

Working Principles

The MC74LCX158DTR2 works by selecting one of the four input signals based on the select input. The selected signal is then routed to the corresponding output. The enable input controls the overall operation of the device. When the enable input is high, the multiplexer is active, and the selected input is passed to the output. When the enable input is low, the outputs are in a high-impedance state.

Detailed Application Field Plans

The MC74LCX158DTR2 can be used in various applications, including:

1. Data Multiplexing: It can be used to select between multiple data sources and route the selected data to a single output.
2. Signal Routing: It can be used to switch between different signals and route them to different destinations.
3. Address Decoding: It can be used in address decoding circuits to select specific memory locations or peripheral devices.
4. Logic Function Implementation: It can be used to implement complex logic functions by combining multiple multiplexers.
