Overview
The HEF4051BT is an 8-channel analog multiplexer/demultiplexer integrated circuit produced by NXP USA Inc., now part of Nexperia. This device is a single-pole octal-throw analog switch (SP8T) that is suitable for use in both analog and digital 8:1 multiplexer/demultiplexer applications. It features three address inputs (A0 to A2) and an active LOW enable input (E), allowing for the selection of one out of eight independent inputs/outputs.
