Working Principles

The CD74HC138M96 operates based on the principle of binary decoding. The three address inputs (A0, A1, and A2) receive binary information, which is then decoded to activate one of the eight output lines (Y0 to Y7). The enable inputs (E1, E2, and E3) control the operation of the decoder/demultiplexer.

Detailed Application Field Plans

The CD74HC138M96 finds extensive use in digital systems that require decoding and demultiplexing functions. Some specific application areas include:

1. Address decoding in microcontrollers and microprocessors
2. Memory selection in computer systems
3. Data routing in communication networks
4. Signal demultiplexing in audio/video equipment
5. Control signal generation in industrial automation
