Working Principles

The 74HCT138PW-Q100,11 is a 3-to-8 line decoder/demultiplexer. It takes a 3-bit binary address as input and selects one of the eight outputs based on the address value. The active-low enable inputs (/E1, /E2, /E3) control the output selection. When an enable input is low (logic 0), the corresponding output is enabled, and when it is high (logic 1), the output is disabled.

Detailed Application Field Plans

The 74HCT138PW-Q100,11 can be used in various applications, including: 1. Address decoding in microcontrollers and microprocessors 2. Memory selection in digital systems 3. Data routing in communication systems 4. Signal demultiplexing in audio/video equipment 5. Control logic in industrial automation
