Working Principles

The HEF4051BP,652 is a CMOS analog multiplexer/demultiplexer IC. It uses a combination of control inputs (S0, S1, S2) to select one of the eight input channels (Y0-Y7) and connect it to the common output/input pin (Z). The enable input (E) controls the operation of the IC. When E is high, the IC is enabled, and the selected channel is connected to the common pin. When E is low, all switches are turned off, isolating the common pin from the channels.

Detailed Application Field Plans

The HEF4051BP,652 IC finds applications in various fields, including:

  1. Audio/Video Signal Routing: Used in audio/video equipment to switch between different input sources.
