Working Principles

The CD74HC4515M96E4 is a decoder/demultiplexer integrated circuit that converts a 4-bit binary input into one of the 16 output lines. The input lines (A0-A3) determine which output line is activated. The enable pins (E1-E4) control the operation of the decoder. When the enable pin is high, the decoder is active and responds to the input signals. When the enable pin is low, the decoder is disabled.

The CD74HC4515M96E4 uses CMOS technology, which allows for high-speed operation with minimal propagation delay. The Schmitt-trigger inputs provide noise immunity, ensuring reliable decoding even in noisy environments.
