Working Principles
The 74HC4514DB,112 is a decoder/demultiplexer IC that converts a 7-bit binary input into a corresponding active-low output line. The input lines (A0-A7) represent the binary value to be decoded, while the enable input (E) controls the output lines (Q0-Q7). When the enable input is high, the output lines remain inactive. However, when the enable input is low, the output line corresponding to the binary input becomes active-low.
Detailed Application Field Plans
- Address decoding in microcontrollers and microprocessors
- LED matrix control
- Data routing in digital systems
- Multiplexing and demultiplexing applications
- Signal selection and distribution
