Working Principles

The SN74ALS153D is a dual 4-line to 1-line data selector/multiplexer. It selects one of the four input lines based on the control inputs (A0-A3, B0-B3) and outputs the selected data on the Y pin. The E (Enable) input controls the operation of the device. When E is high, the device is enabled, and the selected data is output. When E is low, the device is disabled, and the output is in a high-impedance state.

Detailed Application Field Plans

The SN74ALS153D can be used in various applications, including:

1. Data multiplexing in digital communication systems
2. Address decoding in microprocessors
3. Data routing in computer networks
4. Signal switching in test equipment
5. Data selection in industrial automation systems
